Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide: Insights and Implications

Historical Development

The path to Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide starts with the broader search for ionic liquids capable of stable operation under harsh chemical environments. Early research focused heavily on quaternary ammonium salts. By the late 1990s, trialkyl-substituted ammonium systems caught attention because their bulky groups provided impressive stability. Adding a methyl group on the nitrogen in the presence of three n-octyl chains allowed researchers to sidestep issues like water absorption and limited solubility. Bolstered by relentless experimentation, the industry steered these compounds toward a variety of roles, from catalysis to energy storage. Today, the double-barreled counterion bis(trifluoromethanesulfonyl)imide boosts solubility and helps tune electrochemical behavior, reinforcing its usefulness beyond a mere lab curiosity.

Product Overview

This compound belongs to a group of quaternary ammonium-based ionic liquids built for tasks demanding both hydrophobic and thermally-resistant features. Its long n-octyl chains deliver a low melting point and high viscosity. It's not cheap to make or easy to handle, but researchers and engineers prize its performance. Among ionic liquids, this one draws attention for its broad electrochemical window, barely-there volatility, and readiness to mix with both organics and certain polymers. This blend of technical features sends it straight into specialized fields rather than mass-market commodities. Labs working on next-gen batteries and separation membranes don’t reach for the off-the-shelf stuff – they’re looking for ionic liquids that refuse to break down, migrate, or react in corners of the periodic table where weaker molecules falter.

Physical & Chemical Properties

Physically, it’s a dense, oily liquid at room temperature, typically showing a faint yellow tinge due to minor impurities. The molecular weight tips the scale well over 750 g/mol. Its viscosity challenges pump systems at lower temperatures, but rises to the challenge required for damping or lubrication where volatility causes headaches. Chemically, the bis(trifluoromethanesulfonyl)imide anion gifts it with chemical stability in aggressively acidic or basic media. Water barely dissolves it, wicking up very little due to the eight-carbon chains blocking hydrophilic interactions. Thermal stability averages out above 300°C in inert atmospheres, long past the breaking point for most organic solvents. As temperatures rise, decomposition tends to generate sulfur and fluorine-containing volatiles, so careful engineering matters in scale-up.

Technical Specifications & Labeling

Manufacturers label Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide with a minimum purity above 98%. Residual water content usually hangs around 500 ppm or less. The technical datasheet breaks down molecular structure, CAS registry numbers, target impurity levels (including halides and unreacted amines), and storage guidelines: low humidity, sealed vessels, away from heat sources. Batch-to-batch consistency gets monitored with NMR confirmation of the ammonium methyl and octyl groups with good baseline separation of the supporting anion peaks. End users scan for nonvolatile residue (often under 100 ppm), as even low-level contaminants can mess with battery electrode performance or membrane properties. The packaging is often amber glass or high-integrity polymer to reduce ion exchange or leaching.

Preparation Method

Getting precise control during synthesis starts at the quaternization of N,N-dioctylmethylamine, often reacted with 1-bromooctane or a similar alkyl halide in polar, aprotic solvents under nitrogen purging. Once the methyltri-n-octylammonium halide emerges, a classic metathesis reaction swaps halides for the bis(trifluoromethanesulfonyl)imide anion. This step relies on maintaining dry and oxygen-free conditions, since water or oxygen can spawn persistent side-products, especially when mixing with lithium bis(trifluoromethanesulfonyl)imide used as the counterion source. Careful purification via repeated washing, extraction, and vacuum drying follows, because trace halide or moisture would compromise the stability ionic liquids promise in sensitive applications.

Chemical Reactions & Modifications

Focused on chemical robustness, this ammonium compound sidesteps easy alkylation or nucleophilic displacement on the cation because bulky octyl chains shield reactive centers. The anion, stuffed with electron-withdrawing sulfonyl groups, rarely acts as a donor or acceptor, so standard organic modifications leave it alone. Reactivity most often pops up during stress testing: high voltages might drive slow fragmentation, while strong Lewis acids draw out dimerization or degradation byproducts. Tinkering with the alkyl groups in the starting amine can nudge properties like melting point and polarity, but chemists value the baseline provided by the methyl plus trioctyl pattern for applications in electrochemistry and organic synthesis. When disruption does happen, spectroscopic traces guide process optimization to minimize unwanted transalkylation or decomposition.

Synonyms & Product Names

This compound shows up under a range of aliases reflecting its detailed structure. Commercial packages use names such as Methyltri-n-octylammonium NTf2, Methyl trioctylammonium bis(trifluoromethanesulfonyl)imide, or abbreviated as [N8881][NTf2]. Research circles sometimes refer to it by its IUPAC names or in acronyms, which can confuse database searches or procurement efforts unless users stick to verified CAS numbers or supplier batch references. It’s not unusual to see the “ionic liquid” descriptor tacked on, as many catalogues position this for specialty solvent work rather than routine salt chemistry.

Safety & Operational Standards

Working with Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide calls for precautions similar to other hydrophobic ionic liquids. It rarely vaporizes under ambient conditions, but its slow biodegradation and environmental persistence have led to more scrutiny in waste streams. Labs require PPE — gloves and safety glasses at minimum — with fume hoods preferred for larger quantities. Because of its high affinity for organics, spills on benchtops linger and demand nonpolar solvent cleanup. No solid evidence links this ammonium salt to acute toxicity through skin absorption, but long carbon chains and fluorine-bearing groups discourage careless handling. Waste must enter segregated collection streams, marked for high-temperature incineration or chemical destruction. Regulatory bodies like REACH and OSHA cast a wary eye, pressing for more granular toxicity data beyond cell culture or rodent models.

Application Area

Innovation in energy storage drives a lot of the demand for specialty ammonium ionic liquids. In lithium-ion batteries, engineers aim for electrolytes that survive high charge-discharge rates and wide voltage swings. Here, Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide adds both stability and low reactivity, staving off electrode erosion and unwanted side reactions thanks to its robust anion and physical bulk. In separation science, its hydrophobic core and chemical inertia allow designers to craft membranes that resist swelling or fouling while remaining flexible. Outside those flagship arenas, some catalytic systems adopt this ionic liquid to extend reaction life, reduce vapor emissions, and open the door for easier product extraction. It rarely lands in consumer products, but in the hands of translational researchers, the results shape industrial practice down the pipeline.

Research & Development

The R&D landscape teems with experiments tweaking this molecule. Some studies dive into how swapping the methyl group for ethyl or butyl shapes conductivity or partition coefficient. Others stretch its use in redox mediators or dig deep into impurities and their effects during long-term use in batteries or chemical reactors. Specialists worry that early hype around the “green” nature of ionic liquids fails to recognize persistent traces and slow breakdown — so current research steers toward lifecycle analysis and recovery from end-of-life equipment. Collaborators from academia and industry swap data on pilot-scale syntheses, cross-referencing findings about process yields or impurity removal to shave costs without sacrificing properties. The push for recyclable, lower-toxicity ionic liquids sometimes runs against performance requirements, and balancing that tradeoff stays front-and-center for chemical engineers.

Toxicity Research

Digging into the toxicology, long-chain ammonium salts split opinion. Short-term studies on cell cultures and aquatic life suggest low acute toxicity, but accumulation in soil and water triggers concern about chronic exposure, particularly for organisms lacking efficient metabolic clearance mechanisms. Decomposition products — with fluorinated and sulfonated fragments — call for closer scrutiny, given their mobility and persistence in the environment. Humans almost never encounter it outside research or manufacturing, but carelessness could lead to unknown skin or inhalation effects, and the lack of human epidemiological data spurs calls for pre-exposure screening and detailed metabolism studies in vertebrates and invertebrates alike. Setting workplace exposure limits begins with the principle of minimizing direct and indirect exposures, so responsible production lines invest heavily in closed systems.

Future Prospects

This ionic liquid faces a future tied to the fate of advanced electrochemical systems. If solid-state batteries or flexible photovoltaics enter mainstream production, demand for high-stability, hydrophobic electrolytes like Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide stands to grow. At the same time, engineers and regulators push for more transparent environmental impact reporting and materials designed for circularity rather than single-use performance. Whether greener precursors and closed-loop recycling can match the durability of current molecules stays an open question; a mix of regulation and market pressure will settle that. Researchers testing alternatives keep feeding back into process improvements, shaping a more cautious but ambitious approach to specialty solvents and electrolytes with real-world impact. Instead of resting on its laurels, this molecule’s journey continues, one carefully weighed risk and reward at a time.



What is Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide used for?

Why This Chemical Draws Attention

People call it an ionic liquid, but to most of us, it looks just like a fancy bottle in a lab refrigerator. Its real-world reach stretches further—battery research, chemical processing, and specialty manufacturing. It’s not something you run into in the grocery aisle, but it shapes some surprising corners of the world.

Power for the Next Generation

Cutting-edge labs keep searching for ways to pack more power into batteries—especially for electric cars and portable devices. This compound matters because it shuts down old limits. It resists breaking down even at high temperatures, and it doesn’t carry water or evaporate easily. That means batteries run longer and safer, especially when things heat up.

Scientific reports show that using it as an electrolyte (the part that lets current move inside batteries) raises both performance and safety. Traditional lithium-ion batteries come with risks—swelling, leaks, even fires. This ionic liquid stands up to those problems, giving engineers new options. As someone who saw a phone battery puff up, I know how important these advances feel.

Cleaner Chemistry, Smarter Processing

Industries face strict rules on environmental impact these days. Methyltri-N-Octylammonium bis(trifluoromethanesulfonyl)imide handles separation processes in the chemical industry. Refineries use it to pull out metals like lithium or rare earths while creating less toxic mess and less waste than traditional solvents. The liquid form makes recycling and reuse possible, cutting down runoff.

In pharmaceuticals, the hunt for purer, more precise reactions never ends. Traditional solvents bring lots of safety risks for workers. This compound’s low volatility means fewer fumes, and its chemical stability means you don’t have angry exothermic reactions making safety officers lose sleep. When you see stricter occupational limits and growing health expectations, it makes sense to shift to safer materials like this one.

Environmental Hurdles and Workplace Realities

Every chemical with a name this long brings questions about persistence in the environment. Its resistance to heat and reactions means it tends to stick around. Environmental chemists raise fair concerns about what happens after use. Companies should step up by testing for long-term environmental impact and exploring ways to break it down after its job is done.

Serious scientific work needs strong oversight—especially with emerging chemicals. Regulators, industry leaders, and researchers have a role to play. Transparency makes a difference. Makers should spell out what happens if spills hit the ground or run into water systems. Government agencies must track usage and set exposure limits based on solid evidence. Giving regular workers easy-to-read safety sheets, not just dense technical jargon, makes workplaces safer.

What Might Move the Needle

Shifting to safer, more sustainable chemistry is rarely about a single magic bullet. New options like this ionic liquid help break old patterns. Teamwork between battery companies, green chemists, and engineers will show whether it earns a regular place in industry. Funding trials that test recyclability, and backing environmental studies, lays the groundwork for scaling up responsibly. As industries keep searching for more power with less pollution, substances like methyltri-n-octylammonium bis(trifluoromethanesulfonyl)imide lead to the sort of progress that truly matters.

What is the chemical formula and structure of Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide?

Getting Into the Chemistry

Something about chemical names with fifteen syllables always catches my eye. Methyltri-N-octylammonium bis(trifluoromethanesulfonyl)imide takes the cake. Folks in industry call it ionic liquid royalty. The formula isn’t just a badge for the chemist’s wall. It’s a roadmap: C27H60F6N2O4S2. You follow the carbon skeleton and those long octyl chains—think of them like octopus arms giving the molecule its oily personality. Add in the nitrogen at the core (thanks to that ammonium group) and you get a molecule sporting both flexibility and a real knack for working with other compounds.

Why This Structure Matters

Ions don’t always behave the way textbooks suggest. The cation here, methyltri-n-octylammonium, holds a nitrogen center bonded to one methyl group and three octyl groups. The cation looks a lot like a tripod with one short leg and three long legs, making it lopsided enough to dodge crystal packing and stay liquid at room temperature. The anion, bis(trifluoromethanesulfonyl)imide—abbreviated TFSI-—runs as one of the most popular anions in ionic liquid world because those two bulky, electronegative trifluoromethanesulfonyl groups attached to a central nitrogen yield top-notch solubility and chemical resilience. Chemists admire this—practically worship it—since it means fewer problems with reactivity.

What Makes This Salt Stand Out

I found that trying to make traditional organic salts work in solvents feels like swimming upstream. Solubility hits a wall. Adding length to the alkyl chains (like those octyl groups) and picking the right anion (like TFSI-) lets the salt dissolve almost anywhere. These traits push methyltri-N-octylammonium bis(trifluoromethanesulfonyl)imide into all kinds of applications from electrochemistry to extraction science. As batteries keep demanding more stable electrolytes, researchers circle back to salts like this one because the structure resists both moisture and oxidation. That’s not just theoretical—plenty of companies and academic labs swear by it.

Science Means Solutions

The main challenge with large ionic liquids revolves around the balance between performance and sustainability. Manufacturing these fluorinated anions, for example, isn’t lightweight on the environment. Better synthetic routes can cut waste and trim side products. I once talked to a team using enzymatic catalysts in place of traditional acid-based synthesis; the product purity shot up, and production waste fell.

Waste also creeps up during downstream processing. Greener solvents, tighter distillation, and column recycling all save on both budget and landfill. The new trend involves life-cycle assessment right at the design stage—seeing how every part of the process will impact the world before the first batch even leaves the lab.

Looking at safety nets: this salt avoids the volatility of many older chemicals, so indoor air stays cleaner. Proper ventilation and containment, plus good storage protocols, all help keep chemists healthy. Even with green chemistry advances, no formula changes the need for gloves and goggles—the basics still matter.

Toward Smarter Chemistry

At its core, the story of this compound isn’t just about new molecules—it’s about smarter choices. By combining robust chemical knowledge with a real awareness of practical needs, we create safer, more flexible, and more responsible options. That approach pays off in the lab, the factory, and the world outside.

What are the safety and handling precautions for this compound?

Respecting a Compound’s Risks

Every chemical comes with its own hazards. Even substances found at home may surprise you with the trouble they stir up once out of their usual spot. In labs and factories, people get hurt not from the most deadly substances, but from familiar ones handled carelessly. The main lesson is: never take shortcuts around safety, even with chemicals that seem harmless.

Personal Protective Equipment is Non-Negotiable

Forget about "just this once" when it comes to gloves, goggles, or lab coats. Chemicals splashing in an eye, soaking into skin, or getting inhaled do real damage—sometimes burns, sometimes nerve trouble, sometimes cancer years later. Old-timers know what it’s like to rinse an acid burn that eats deeper by the second, or deal with headaches from vapor. Simple choices, like wearing a face shield and nitrile over latex gloves, often draw a clear line between a safe shift and an avoidable trip to the doctor.

Label Everything, Store It Properly

Mislabeling sits at the root of plenty of scary stories. In one lab, a friend poured what they thought was water into organic waste, sending fumes across the room. The real culprit was a similar-looking clear solvent, left with no name. Always write the full name and concentration, and double-check expiry dates. Storing acids away from bases, oxidizers away from organics, and keeping flammables in a vented cabinet stops a small accident from turning major.

Ventilation and Good Housekeeping Matter

Poor airflow leads to more than just bad smells. Without a proper hood or exhaust, gases build up. I once watched a sealed jar crack from inside pressure, waking everyone up in a second. Use the fume hood, close the sash, and don’t block vents. Spilled powder or puddles need a quick, careful cleanup, using the right neutralizer or absorbent. Sweeping crumbs under the bench means trouble for the next person—and maybe yourself.

Know the First Aid Steps

Everybody sounds confident about emergency showers and eyewash stations until they need them. It pays to walk through the drills. If someone ingests a chemical, don’t make them vomit. If eyes are burning, rinsing nonstop for 15 minutes makes a massive difference. Have emergency numbers posted where they can’t be missed. The value of a quick, calm response outweighs anything fancy.

Disposal is a Shared Responsibility

Dumping chemicals down the drain or tossing them into regular trash isn’t only illegal—it poisons groundwater, endangers waste workers, and damages treatment facilities. Follow the local rules. Group waste by type, mark it plainly, and keep incompatible stuff separate. Chemical leftovers rarely vanish—they pop up in the environment later, sometimes with bigger consequences. Take disposal as seriously as the lab work itself.

Training and Attitude Count Most

New folks need hands-on instruction from someone who’s made and learned from mistakes. No routine replaces thoughtful attention: double-check labels, ask questions if uncertain, and slow down if something feels off. Safety becomes a habit with repetition and shared stories about close calls. No classroom lecture takes the place of gut-level respect for a chemical’s potential.

How should Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide be stored?

Understanding the Challenge

Methyltri-N-Octylammonium Bis(Trifluoromethanesulfonyl)Imide draws attention in labs for its versatility in electrochemistry and catalysis. Between the long name and specialized uses, this compound delivers solid science but expects respect in return—especially around storage.

Respecting the Chemistry

This substance belongs to the family of ionic liquids. Many ionic liquids offer thermal stability and interesting properties, but store them like table salt and sooner or later, you regret it. From my years of lab work, keeping a compound with perfluorinated anions away from unnecessary moisture or direct sunlight counts as common sense. Water can mean more than just spillage or stickiness; for some salts, it means chemical changes and headaches during the next experiment. That holds true here.

The Lab Fridge Is Not a Cure-All

Refrigeration does not help if condensation builds up inside the bottle. Once, my careless handling cost weeks of sample prep: I’d pulled a similar ionic liquid out of a fridge, left the lid off, and humidity did its worst. After that, silica gel became a friend. Using a tightly sealed amber glass bottle protects the compound from stray light. A simple silica gel packet dropped inside the storage container absorbs moisture without complicating things. This isn’t overkill—it’s just respect for material that costs good money and grants reliable results only if handled right.

Temperature and Environment

Normal room temperature—think 20–25°C—usually works well for ionic liquids like this one. Avoiding direct heat sources and sunlight keeps degradation at bay. I tossed a bottle on a sunlit windowsill once, and the haze that followed made clear that UV rays don’t play nice with most perfluorinated compounds. Given the value and price of this material, skipping sun exposure is a small price for long shelf life.

The Importance of Labeling and Safety

Too many researchers assume the label provided by a supplier tells the full story. In practice, I’ve been bitten by old labels or lazy note-taking—simplest fix is to date every bottle at the time of opening and note down storage conditions. It only takes a sharpie and a minute, and then you aren't left guessing months down the line. Knowing who last opened a bottle, what date you cracked the seal, and which batch sits inside prevents not just waste but also possible safety incidents. With fluorinated compounds, reading the Material Safety Data Sheet means more than checking boxes; it gives another chance to spot nasty surprises or overlooked incompatibilities.

Ventilation and Spill Response

Even the safest lab spaces can face accidental spills. Choosing a site away from strong acids, reactive metals, or open flames means you aren’t gambling every time you reach for the bottle. Placing the compound in a ventilated storage cabinet that handles organics adds another layer of caution. That may sound boring, but it keeps you from paying for a single moment's oversight with a shutdown or health scare.

Final Thoughts: Small Habits, Big Payoff

The best solution for protecting valuable chemical stocks boils down to habit. Clean the workspace before opening the bottle. Wear gloves—fluorinated sulfonyl groups reward carelessness with irritated skin. Tighten the cap. Drop in a silica packet. Place the bottle far from sunlight and heat. Date it, track it, and respect the chemistry. These small steps save money, frustration, and sometimes health. After a few mistakes, even the busiest researcher can confirm: smart storage always beats damage control.

Is this product available in different purity grades or packaging sizes?

The Impact of Purity on Work and Results

Every time a project lands on my desk, I look for the details. What purity are we working with? Is the volume enough? Lately, these questions have turned into something more than box-checking. For researchers and manufacturers alike, purity isn't just a label. Choosing among different grades can make or break an experiment or batch. Laboratories pushing the boundaries of medicine depend on higher-purity reagents, knowing that a single contaminant could skew results. Food and beverage producers, on the other hand, balance quality and cost, needing grades that meet safety regulations without sending bills through the roof.

I once watched a team waste two weeks discovering a reaction failed because the available reagent carried an impurity. Two departments ordered the same chemical, but slightly different grades. One batch passed, the other didn't. They traced the problem back to a small difference in purity level. The lesson stuck: you get only as much accuracy, repeatability, and safety as the weakest component allows.

Why Packaging Size isn’t “Just Packaging”

The debate over bottle sizes seems small — until you realize how many labs run on razor-thin budgets. Graduate students grimace at half-used drums gathering dust while startups hunt for the elusive 50-gram bottle that keeps their pilot project under budget. No one likes to buy more than they need, and large-scale manufacturers get frustrated if suppliers only offer tiny, awkward containers.

I’ve seen too many researchers forced to compromise. They buy chemicals in bulk and fight clumps caused by exposure, or they ration out the last milligrams, risking inconsistency. There’s an environmental angle, too. Smaller bottles often result in less waste for those making smaller batches or working in fields where shelf life and disposal play a huge role.

Real-World Choices: The Trade-Offs

Not every product comes with a wide menu of options. Some suppliers stick to just one or two purities and package sizes. This limits flexibility, raises costs, and sometimes pushes labs toward substitutes that don’t quite fit their protocols. It’s easy for a company to say that it “offers multiple grades and packaging options,” but in reality, not every market or customer sees those benefits.

Flexibility isn’t just convenient; it’s often essential. Schools, medtech firms, and electronics makers each look for packaging and grades that suit unique needs. Without compatible options, progress slows and costs tick upward. I’ve watched teams lose momentum because they couldn’t get the right grade in the right size, forcing them to dilute or repackage — and double their workload.

Building Better Access

A solution looks simple: suppliers who commit to several grades and sizes can open doors for new innovation. Direct conversations matter here. Many suppliers adjust their offerings based on what everyday users report from the field. Companies investing in broad catalogues foster loyalty and help a wider range of buyers, from local schools to multi-national corporations. For industries seeking better research, higher safety, and greater efficiency, access to variety is more than a convenience — it’s a necessity.

The next time I shop for reagents, I’ll remember the wasted time and effort that comes from forcing the wrong fit. Seeing suppliers who actively expand their grades and packaging sizes signals a focus on real-world workflows, not just warehouse logistics.
