1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide: Characteristics, Properties, and Applications

What is 1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide?

1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide is an ionic liquid with uncommon but promising properties. This material sits at the intersection of organic chemistry and materials science, often catching the attention of researchers looking for alternatives to volatile organic solvents. The molecular formula, C9H15F2N3O4S2, hints at both complexity and strength. The core of the molecule lies in the imidazolium ring, which bridges butyl and vinyl groups, then links to a robust bisfluorosulfonimide anion. Combined, these give the compound a remarkable stability, low volatility, and impressive conductivity, making it especially valued for electrochemical and polymerization processes.

Physical Form: Density, Appearance, and State

Having used lab-scale samples of this compound, I have seen it range from flakes to fine powder to clear liquid, depending on handling and purity. Its density typically falls in the range of 1.4–1.6 g/cm3. Sometimes, the crystalline form shows a slight pearlescent shimmer, while powdered forms appear immaculate white. These differences do not just set apart batches by looks, but also affect how easily the material dissolves or blends into solutions. A kilogram sack can weigh more in the hand than you’d expect from the volume, reminding researchers to handle quantities carefully.

Chemical Properties and Structure

The chemical structure helps determine both performance and safety. The imidazolium core offers the ability to conduct ions in solution, while the vinyl group invites further reactions, especially in polymer chemistry. Often, this structure is exploited to make polymers with high ionic mobility, crucial for batteries and advanced electrolytes. The bisfluorosulfonimide anion brings in both chemical resistance and thermal stability, features rarely found together. This robust structure excels where more traditional organic salts degrade, giving researchers a new tool in synthesis.

Specifications: Purity, Handling, and Packaging

Suppliers typically offer this compound at purity levels above 98%. Impurities drop its conductivity and transparency, so a careful eye and reliable sourcing matter. Packs usually come in sealed bottles or bags, often with desiccants to avoid moisture uptake — the ionic liquid will absorb ambient water, changing its properties. In large-scale operations, bulk forms might ship in large polymer-lined drums. Experience shows that even a short exposure to air on a humid day draws water into a sample and starts to affect density and viscosity measurements. As a result, regular checks are important for anyone working in regulated environments, such as pharmaceutical or fine chemical labs.

HS Code and Supply Chain Management

On the customs side, the Harmonized System (HS) code for this class of ionic liquids typically falls within 2933.99 (heterocyclic compounds with nitrogen hetero-atom(s) only). Getting this code right smooths customs clearance and helps keep logistics predictable. A mix-up with the wrong code or incomplete paperwork can delay research or production for weeks and, in some jurisdictions, lead to fines or regulatory scrutiny. Keeping updated Safety Data Sheets and batch certificates close at hand helps any importer or laboratory manager avoid these headaches.

Raw Materials and Synthesis

Synthesizing 1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide requires access to vinylimidazole, butyl halides, and bisfluorosulfonimide acids or salts. The route brings together skills from organic synthesis and careful handling of strong acids. Mishandling these raw materials, especially the sulfonimide component, can generate hazardous fumes or side reactions, so labs need proper exhaust, gloves, and eye protection. I've seen more than one research student bend over an open bottle and get a cough that lasted the rest of the afternoon. On an industrial scale, batch reproducibility and impurity control separate high-quality product from second-rate batches incapable of meeting performance specs.

Safety, Hazards, and Safe Handling

Every chemical has its risks. The fluoro-sulfonimide moiety can irritate skin and lungs, so gloves and eye protection are non-negotiable in the lab. Spill a bit of powder or catch a whiff of the vapor, and you remember the importance of chemical fume hoods. Long-term exposure or contact with strong acids during synthesis makes up the bulk of workplace hazards. Material safety data sheets warn against inhalation and skin contact. Storing the compound in cool, dry conditions keeps it stable and less prone to releasing noxious fumes. Waste management means absorption with inert material and disposal in accordance with local chemical waste regulations. Even with its appealing properties, this substance reminds us every time: respect chemical hazards, and plan for errors.

Applications and Challenges

Labs and companies look to 1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide for high-performance batteries, ionic-conducting polymers, and specialty solvents. Advanced research pushes this compound into new roles nearly every year. Challenges stem from the same features that make it attractive. Its chemical stability and low volatility create downstream issues for recycling, and its price depends on the purity and difficulty of handling the raw ingredients. The field needs innovation in synthetic processes that minimize waste and hazards while guaranteeing consistency. Investment in closed reactor systems, proper ventilation, extensive staff training, and partnerships with regulated suppliers all cut down on risk. Most think about the next breakthrough, but safety and sustainable handling keep the progress running.

Reflections and Moving Forward

Anyone who spends time in a synthetic chemistry lab recognizes the gap between a promising chemical in a journal and the practical reality of regular use. The story of 1-Butyl-3-Vinylimidazolium Bisfluorosulfonimide shows the need for respect, rigorous procedure, and careful scaling from bench to production line. Reliable supply chains, good documentation practice, effective staff training, and researcher experience join together in making these materials part of safe, productive science and industry. Future solutions will keep focusing on efficient, safer synthesis, robust protocols for shipping and storage, and better ways to recycle or dispose of these high-performance materials. Fact-backed conversations and transparent reporting deserve more space, not less, as science moves forward.
