1-Butylsulfonic-2,3-Dimethylimidazolium Trifluoromethylsulfonate: Looking Beyond the Laboratory

Historical Development

Curiosity drives chemistry into new spaces. Years ago, chemists craved alternatives to volatile, hazardous solvents, especially as environmental and safety concerns got louder. Ionic liquids, especially imidazolium compounds, gained speed in both academia and industry. The butylsulfonic-2,3-dimethylimidazolium cation linked up with trifluoromethylsulfonate (OTf) anion marks a milestone sparked by these early ionic liquid successes. People realized tweaking the side chains on the imidazolium would help shape everything from stability to solubility, which led to molecules like this one collecting attention for their unique mix of structure and function. Instead of just being a lab curiosity, this compound carved out its name in discussions for green chemistry and high-demand industrial processes, hitting the scene as the ’90s and early 2000s chemists grew hungrier for non-flammable, low-toxicity, air-stable solvents.

Product Overview

1-Butylsulfonic-2,3-dimethylimidazolium trifluoromethylsulfonate lands in the catalogues of specialty chemical suppliers thanks to its ionic liquid nature. It brings together a bulky organic cation and a charge-balancing, weakly coordinating anion. Among the crowd of ionic liquids, this one stands out because it handles extremes that break down weaker competitors—resisting significant thermal shocks and tolerating strong acids or bases without falling apart. Pure batches often show up as viscous, clear to pale yellow liquids with a subtle odor, which usually fades as the material equilibrates in open air. Unlike sticky, colored byproducts left over from less optimized methods, high-quality product holds to demanding standards for purity and water content.

Physical & Chemical Properties

Interest in this ionic liquid starts with its melting point, which sits comfortably below room temperature, basically guaranteeing it stays in liquid form except under extraordinary storage conditions. That flexibility matters in real-world labs where temperature swings happen. Its density tends to hover near 1.3 g/cm³, suggesting it won’t float, but sinks in water—a helpful trait in separation processes. Vapors barely show since volatility is nearly zero in typical environments, a huge bonus compared to older, more dangerous organic solvents. Chemically, it refuses to hydrolyze even in moist settings, so storage and handling call for less fuss. The OTf anion does double duty, serving up solubility boost for both organics and long-chain organic molecules, unlocking mixing options for otherwise stubborn reactants.

Technical Specifications & Labeling

A well-documented batch comes in labelled bottles, listing the chemical’s complete IUPAC name and a minimum purity of at least 98%. Toxicological precautions head the safety sheet, along with clear pictograms if the supplier aligns with GHS standards. Typical technical data includes moisture content measured by Karl Fischer titration (<0.2% recommended), residual halide tests, and confirmation of acid–base neutrality—usually pH 6–7 in 0.1 M solution. Some distributors include the CAS number, storage advice (cool, dry shelf preferred), and incompatibility warnings. The product label and accompanying certificate of analysis give users reads on trace metals and confirm absence of common interfering ions, both points crucial to research-scale and industrial processes where even slight contamination crashes whole syntheses.

Preparation Method

Practical synthesis starts out with 2,3-dimethylimidazole reacting alongside 1,4-butane sultone under basic conditions, producing the 1-butylsulfonic-2,3-dimethylimidazolium intermediate. Neutralization with trifluoromethanesulfonic acid follows, forming the final ionic pairing. This process tends to generate significant heat—safety controls keep workers away from accidents common to exothermic quenching. Purification by repeated washings and vacuum drying leaves a clean, nearly colorless oil. Standard labs rely on careful titration or NMR checks to gauge conversion efficiency and hunt down residual starting materials. Every experienced bench chemist develops a knack for judging whether a synthesis run gave a decent product simply by the liquid’s look and feel, a skill that sometimes beats instruments in flagging trouble before analytical results come back.

Chemical Reactions & Modifications

This ionic liquid rarely sits still in a flask. Chemists push it to new areas through quaternization—swapping cation arms swaps reactivity profiles, a trick that tunes properties for specific reactions. Its OTf anion acts as both a silent spectator and, sometimes, a participant, handling nucleophilic substitutions when needed. The robust sulfonic group on the cation holds up under severe oxidative conditions; some researchers fix it onto support surfaces, crafting immobilized catalysts for continuous-flow reactors. Its stability enables direct participation as a reaction medium, solubilizing everything from transition metals to stubborn organic solids. Sometimes, chemists take the base cation, layer on tailored side chains, and build new generations of task-specific ionic liquids, each leveraging the legacy of the butylsulfonic-2,3-dimethylimidazolium core for unusual solvation strengths and low toxicity.

Synonyms & Product Names

Besides its formal IUPAC title, this compound shows up on shipments and order lists under names such as BSDMIm OTf or 1-BS-2,3-DMI triflate. Some catalogs abbreviate further, listing it under cation–anion pairs using shorthand: BuSO3-DMI+ OTf-, giving researchers the precise identity in compact form. Seasoned bench chemists learn these short names by heart to avoid confusion—forgetting the subtle difference between similar acronyms sparked more than one shipment of the wrong material in rushed lab settings.

Safety & Operational Standards

While this ionic liquid sidesteps major volatility hazards seen in flammable organics, it doesn’t get a free pass. Eye and skin contact can trigger irritation, so most labs enforce gloves and goggles as non-negotiable. Spill control involves absorbents, never water spray, since the triflate group prevents hazardous exotherms but still drags contaminants wherever it flows. Proper containers get tightly sealed, since trace humidity, though not destructive, can skew sensitive analytical measurements. I remember one midsummer lab day when a careless stopper let enough moisture into a reaction bottle to knock down yields—one misstep, and hours of careful planning collapsed. Disposal rules demand treatment as organic chemical waste, often incinerated under controlled conditions to limit release of fluorinated breakdown products. Safety trainers emphasize that despite a tame risk profile, untested mixtures or thermal extremes can create new hazards, so routine chemical hygiene never slips.

Application Area

Researchers turn to this ionic liquid as a game-changer in organic synthesis, electrochemistry, and materials science. Its resilience opens doors for tough oxidation or reduction steps where solvents like DMSO or DMF break down. In battery research, its ions conduct charge while standing up to the rigors of extended cycling, chasing higher energy densities without flammability risks. Catalysts dissolved inside often achieve higher turnover numbers since the medium keeps reagents dissolved and stabilized. The solvent properties help isolate tricky natural products, making extraction runs less toxic and more reproducible. Some teams mix it into polymer electrolytes, stretching plastics into new realms of thermal and mechanical stability. I’ve watched colleagues breathe easier troubleshooting finicky reactions, knowing the solvent won’t vanish or ignite under normal bench conditions.

Research & Development

This ionic liquid draws collaborations across chemists, engineers, and materials scientists, all betting on its stable backbone and adaptability. Teams dive deep into tailoring cation and anion combinations for niche applications, such as chiral synthesis or selective separations. Big chemical companies sponsor studies, eyeing cheaper production routes and thriftier recycling methods that cut costs and reduce environmental impact. Universities chase after its potential as a solvent for carbon dioxide and other greenhouse gases, possibly dovetailing into future climate mitigation efforts. Each year, more papers chart ways to wring better yields, greener processes, and smarter material interfaces using this liquid—both as a reaction medium and sometimes as a subject for computational modeling, where its charge distribution shakes up familiar physical theories. New collaborations seem to pop up every season, driving even more creative uses well past what early adopters dreamed.

Toxicity Research

Assessments began as soon as ionic liquids looked likely to leave the lab bench and head for scale. Researchers found that—compared with legacy solvents—this compound doesn’t easily bioaccumulate or volatilize into working environments, a relief in shared research spaces. Even so, both acute and chronic exposures pose open questions. Studies show limited cytotoxicity at low concentrations, but tests in aquatic systems hint that discharge into waterways, even in dilute form, carries risks to invertebrate ecosystems. Animal cell culture work provides hints on possible irritant effects; no long-term carcinogenicity data has cleared regulatory review, so prudent practice means never treating any new solvent like water. Industrial health officers track exposure, enforce closed-system handling, and review every batch’s safety sheet for updates that come as more experiments run their courses. Responsible users always stay tuned to the environmental science press for any signals on longer-term environmental persistence.

Future Prospects

Demand for adaptable, non-toxic, and thermally stable ionic liquids keeps manufacturers developing new twists on the butylsulfonic-2,3-dimethylimidazolium trifluoromethylsulfonate backbone. Potential awaits in battery electrolytes designed for solid-state devices, where conventional solvents fail. Scale-up for industrial synthesis keeps chemists hunting for routes to cheaper, less wasteful production, maybe harnessing flow chemistry or bio-based starting materials to ease environmental strain. Questions from regulatory voices around environmental fate and toxicity spur more comprehensive, real-world case studies—each wave of results confirming or refuting past assumptions. Tight academic and industry partnerships should yield next-generation variants tuned for catalysis, environmental extraction, and even unusual heat-transfer systems. As energy storage, environmental cleanup, and precision synthesis mature, ionic liquids such as this won’t be niche tools—they’ll anchor bigger, greener, and safer chemical operations across sectors that barely acknowledged them a decade ago.



What are the main applications of 1-Butylsulfonic-2,3-Dimethylimidazolium Trifluoromethylsulfonate?

Modern Chemistry Gets a Lift from Ionic Liquids

Talk to anyone working in advanced chemical labs and you’ll hear plenty about ionic liquids. 1-Butylsulfonic-2,3-dimethylimidazolium trifluoromethylsulfonate (often called BSMIM OTf) brings a fresh angle to the field. With its solid record for stability and non-flammability, folks in research and industry fields tend to keep it in their toolkits for big, sometimes quietly important jobs.

Catalysis and Green Chemistry

Catalysis shapes the world behind the scenes, from making medicines to keeping cars on the road. BSMIM OTf, with its unique structure, steps in where old-school solvents fall flat. You don’t run into the same volatility or toxicity headaches you get with traditional choices like toluene or acetonitrile. In pharmaceutical synthesis and petrochemical processing, workers see fewer disruptions, and plants spend less money on cleanup plans to deal with spills or residual waste. As someone who’s spent late nights on post-lab solvent disposal, I know firsthand how much hassle these newer solutions can save.

Batteries and Energy Storage

Rechargeable batteries power plenty these days, from family cars to full cities. Stability and ionic conductivity matter. BSMIM OTf brings both—sitting in electrolytes and letting ions flow with far less drama from leakage or breakdown. In the past, finding compatible solvents stalled progress. Now labs see better battery lifespans and fewer worries about fires or leaks. Consumers might not notice the compound’s name, but anyone who’s carried a hot laptop can appreciate cooler-running, longer-lasting gear.

Separation Science and Extraction

Industrial plants separate and clean everything from crude oil to medicine bases. Most old methods burn a lot of energy or rely on harsh chemicals. In some extraction processes, BSMIM OTf helps pick out metals or organic compounds without loading up on dangerous waste. Workers at metal recovery operations can tell you: pulling gold or rare earth elements from electronics or mining waste costs less time and gear thanks to BSMIM OTf. Since energy use drops, the savings do show up on the monthly bills.

Precision Synthesis and Lab Work

Complex organic molecules don’t build themselves. Creating them without nasty byproducts or sluggish reactions takes finesse. BSMIM OTf offers a controlled, predictable setting where molecules line up as intended. Chemists in university labs, synthesizing small batches of specialized compounds, often turn to this ionic liquid for jobs that push boundaries on purity or geometry. My own time running NMR analysis found the results easier to interpret with BSMIM OTf in the mix—less interference, cleaner peaks.

Environmental Footprint and The Way Forward

Every tool brings risks and rewards. For BSMIM OTf, clear wins include fewer emissions and smaller waste streams—something regulations back up. Some critics question the long-term breakdown of ionic liquids, and responsible disposal keeps coming up at environmental conferences. For industry, tracing the full life cycle, from lab sink to river, remains a live challenge. Incentives for greener disposal and more biodegradable solutions push chemists to look for upgrades, but the reality: much of the progress still relies on compounds like BSMIM OTf to bridge to cleaner, safer tomorrow.

Is this product suitable for use as an ionic liquid in catalysis or electrochemistry?

Peering Beyond the Label

Curiosity about using new chemicals in catalysis or electrochemistry grows by the day. The push for cleaner reactions and cost savings puts ionic liquids in the spotlight, often marketed as green solvents or robust electrochemical media. The hype feels real, but no two products play the same role. Every molecule walks a fine line: structure, impurity, stability — they all write the rules for how that liquid behaves.

Experience in the Lab: The Real Test

Years spent huddled over beakers and electrodes reveal some truths you won’t find in glossy brochures. A proper ionic liquid needs to shrug off water, hold its own at high voltages, and avoid turning into sludge on contact with the substrate. More than once, a promising bottle landed on my bench, only to fizzle during basic conductivity tests or stain electrodes during cyclic voltammetry. Some products, pitched as universal, fall short from the first pipette drop.

The Role of Purity and Thermal Stability

Funky trace metals or left-behind solvents drag down catalysis projects, clogging active sites or sending yields in the wrong direction. Electrochemistry brings its own headaches: a nickel ion here, a chloride impurity there, and suddenly your voltage range narrows or electrodes corrode. Researchers have hammered out these concerns in dozens of published studies. For instance, high-purity imidazolium salts often widen the electrochemical window, letting batteries or sensors push for higher output without overheating.

Temperature swings add another stumbling block. Real-world work rarely sticks to room temperature, so liquids that break down at 80°C rarely find lasting use. Some ionic liquids hold together well beyond 200°C, forming the backbone for harsh reaction conditions — a performance mark easy to miss without close attention to stability data.

Viscosity: The Unsung Barrier

Ionic liquids promise plenty, but if they pour like syrup on a cold day, you end up fighting slow mixing, erratic ion transport, and sluggish catalysts. In the lab, high viscosity means more than annoyance — non-uniform mixing locks away reagents, while electrodes see fewer ions. Lower viscosity versions, designed with shorter chains or bulkier groups, give solutions that move, mix, and recharge with less fuss. Peer-reviewed ruminations, like those by Welton and colleagues, show measurable gains in current and efficiency with the right tweaks to viscosity and ion structure.

Navigating Real Risks: Cost and Scalability

Even if a product shines in tiny vials, scaling up causes headaches if prices soar or the supply chain buckles. An ionic liquid measured in grams isn’t always ready for kilograms. Some, made with rare earths or delicate syntheses, inflate budgets fast, so researchers keep a close eye on price sheets and global suppliers before betting a year’s grant. In greener chemistry, price tags and production waste also play starring roles — if one ionic liquid cuts energy costs or recycles better, it leaps ahead of fancier formulas with steeper fees and higher hazards.

Solutions and Forward Steps

Getting the right fit means more than matching a chemical name to an application. Direct lab trials matter — small-scale tests under actual catalytic or electrochemical loads, with careful checks on stability and purity, sort contenders from pretenders. Open communication with suppliers about batch-to-batch consistency goes a long way toward avoiding future headaches. More collaboration helps, too: working with independent labs or tapping into academic research tackles bias and fills data gaps. For anyone looking to make the switch, building these checks into their process turns hype into real, lasting progress.

What are the storage and handling recommendations for this chemical?

The Heart of Safe Storage

Storing chemicals may sound simple. Lock them up, walk away, and hope for the best. That mindset rarely ends well. Every seasoned worker who’s handled a leaky bottle or caught a whiff of fumes where they shouldn’t be knows this is a field with little margin for error. If curiosity ever leads you down the path of reading chemical labels, words like “flammable,” “oxidizer,” or “corrosive” pop up. These labels are real warnings, not legal filler.

Many chemicals can cause fires, explosions, or dangerous reactions if storage goes sideways. Hydrochloric acid and bleach, stored together, drive home why separation matters. Just one lapse can send toxic gas billowing into the air. I’ve seen workplaces assign the youngest crew member to chemical storage—until a close call reminds everyone that storing chemicals safely matters more than convenience.

Practical Steps for Handling

Solid advice: Read the Safety Data Sheet (SDS) before unloading even a single drum. The SDS talks about temperature ranges, humidity limits, and proper ventilation in everyday English. Some chemicals, like peroxides, need to stay away from light and heat because they grow unstable when things warm up. A well-ventilated room isn’t just a nice-to-have; it stops the buildup of invisible, dangerous vapors.

Containers need labels—clear, honest, permanent. Sharpies wash off. Faded stickers lead to mistakes. Labels must match what’s inside, with expiry dates, hazard warnings, and emergency steps where you can see them without reaching for a step stool.

Forget storing heavy acids above eye level; one dropped container could mean chemical burns and a trip to the ER. Shelves meant for weight keep spills low and make scooping up a spill less of a full-body event. Chemical-resistant shelving and trays give you a fighting chance against leaks. Some folks try to get away with regular wood shelves or cardboard. That never ends well in a humid, splash-prone space.

Improving Habits Reduces Risk

People sometimes treat chemical storage as an afterthought in smaller operations. They tuck cleaning agents, paints, and solvents on a back shelf, assuming small quantities mean lower risk. In fact, crowded spaces and poor habits make a fire or health scare more likely. I’ve seen a loose cap and a forgotten rag cause a stench strong enough to clear an entire building.

Organizing chemicals by compatibility—acids, bases, flammables, oxidizers—keeps one mistake from turning into a disaster. Mixing up incompatible chemicals often lands you on the local news. Color-coded shelves and locked cabinets cut down on those mistakes. Training goes beyond a one-page handout. Stories, hands-on practice, and regular walk-throughs sink in far better than dry memos.

Action, Not Assumptions

Regulations exist for a reason, but wisdom doesn’t end with OSHA or local fire codes. Personal vigilance makes the biggest difference, whether you’re in a school lab, hospital, warehouse, or garage. If something smells odd or looks off, trust your senses. Replace worn PPE. Don’t trust out-of-date storage rules. Reliable storage habits should spread from the oldest hand to the newest hire. Investing in safe habits saves money, lives, and the headache of government scrutiny after something goes wrong.

What is the purity and CAS number of 1-Butylsulfonic-2,3-Dimethylimidazolium Trifluoromethylsulfonate?

Getting Specific With Purity

Chemistry isn’t just about molecules—it’s about trust. When you order a reagent like 1-Butylsulfonic-2,3-dimethylimidazolium trifluoromethylsulfonate, purity isn’t just a number on a spec sheet. It’s a signpost for accuracy and repeatability. Labs and industries expect to see purity levels typically in the range of ≥98%. Less pure forms almost always lead to questionable results and wasted effort. If you’ve ever run a series of syntheses only to see your NMR or HPLC reveal unexpected peaks, you know what I mean. Contamination may look small on paper, but it can take the legs out from under a promising reaction—or even an entire process.

It’s a lesson learned early in any bench chemist’s career. I’ve seen researchers spend days re-running reactions, redistilling solvents, chasing down the root cause of variability, finally realizing an impurity in the ionic liquid stole their yield. Large-scale processes end up costing more because an extra 1–2% impurity in such chemicals can alter the desired properties and performance, especially in catalysis and electrochemistry. Every milligram counts.

CAS Number: The Definitive Identifier

If you’re hunting for a substance, nothing provides peace of mind like a firm CAS number. For 1-Butylsulfonic-2,3-dimethylimidazolium trifluoromethylsulfonate, the number is 934158-37-5. That’s more than just a registry number—it’s the gold standard for chemical identification worldwide. Relying on product names or abbreviations leaves too much room for misunderstanding. I’ve seen that play out in procurement mix-ups or even regulatory filings. Two suppliers may describe their product in slightly different ways, but if they both give you 934158-37-5, you know you’re on solid ground.

This matters not only for buying but also for compliance and documentation. Regulations keep tightening, and chemical inventories depend on accurate tracking. Working off the CAS number streamlines audits, hazard communication, and even customs documentation. It’s a small thing on paperwork, but it saves hours (if not days) of chasing ambiguous records years down the line.

Why Standards Matter in Research and Industry

At first glance, obsessing over purity or registry numbers might seem tedious. In reality, those standards form the backbone of reliable science and responsible industry. Synthetic research runs faster when you can count on the quality of what you’re working with. I’ve watched syntheses grind to a halt due to a mystery impurity; a supplier who delivers consistently ≥98% pure product gets loyalty from scientists fast. It’s the difference between a smooth week in the lab and a cascade of troubleshooting.

Transparency about compound identity and purity builds safer working environments. Lab teams rely on accurate safety data sheets (SDS), and those depend on unambiguous compounds. In the larger scale, production sites keep a tight grip on inputs to protect both workers and equipment. Unintentional exposures or equipment wear due to odd impurities belong in the rearview mirror, not the day-to-day.

Looking Forward: Fixing the Gaps

Better digital tracking can support these standards. Integrated inventory systems that match product barcodes to CAS numbers cut down on mix-ups. More suppliers are also posting spectral data and batch analyses online—a step that helps both buyers and end users make informed decisions before using or reselling a chemical.

It only takes one headache—one failed batch, one compliance warning—to understand why facts matter. Commit to verified purities and unambiguous chemical identities, and watch the trouble shrink.

Does this product have any specific safety or toxicity concerns?

Why Safety Matters in Everyday Products

Most people pick up a new cleaner, cosmetic, or supplement without giving the ingredient list a second glance. Trust plays a big role — we hope companies and regulators keep dangerous stuff out of our homes. I learned after a bad bleach reaction as a teenager that this trust sometimes leads to real problems. Whether we’re talking about chemicals in a garden spray, preservatives in food, or nanoparticles in sunscreen, it’s too easy to assume “somebody checked this.” Not every product undergoes close scrutiny before it lands on a store shelf.

The Consumer Product Safety Commission, the Environmental Protection Agency, and the Food and Drug Administration all work hard, but loopholes pop up. Dietary supplements, for example, skip the pre-market review that drugs go through. Many “green” cleaning products use essential oils, which can be harsh allergens for some people despite a natural label. More and more products rely on engineered ingredients with effects we don’t always understand. People trust governments and companies based on headlines and past experience, but oversight varies, and recall systems don’t always catch everything.

Red Flags and Real-World Examples

I worked in a pharmacy and saw lots of kids come in with reactions to new laundry detergents or lotions. The ingredients seemed familiar — surfactants, fragrances, preservatives. Companies change formulas to keep prices low or appeal to a new market, yet no clear warning appears for a family used to the old version. Severity isn’t always obvious from a label or a scent. One of my neighbors found out her “safe for pets” weed control product contains a compound that lingers in soil and causes pups to get sick for weeks.

Some products, especially those from online sellers or new brands, may not see much oversight. Even known ingredients sometimes interact in harmful ways. For instance, mixing certain ammonia-based cleaners with bleach forms toxic chloramine gas. Plenty of people learn this lesson only after coughing or dizziness kicks in. The rise of imported goods introduces more unknowns, since international standards may differ from what’s accepted here.

Ways to Check and Stay Safe

Worrying is easy, but getting informed is better. Look for products that clearly state all ingredients. The shorter the list, the easier it gets to spot harmful substances. Trusted third-party certifications like UL, NSF, or EWG can help, though they don’t guarantee zero risk. Checking for warnings like “keep out of reach of children” or chemical hazard symbols makes a difference. For food or supplements, checking the FDA’s website or MedlinePlus helps spot common side effects and recalls.

One simple step is to do a patch test — try a tiny amount of a new personal care product before using it widely. Any reaction means the rest of the bottle belongs in the trash. For cleaners, use gloves and ventilate the room. For stuff that’s unclear, seek out reviews from trustworthy health websites or social media groups where real people share their experiences. If a doctor or veterinarian warns against something, trust their advice over flashy advertising.

Toward Better Choices

Big companies only change their habits when shoppers ask tough questions. Asking about safety records, demanding full transparency, and pushing for scientific studies encourages honest marketing. Reporting bad reactions helps agencies and others avoid the same issues. Real progress comes when people stay skeptical and share what they learn with the community. Everyday vigilance, open questions, and personal experience all push the market toward safer, better products.
