N-Allyl-N-Methylpyrrolidinium Bis((Trifluoromethyl)Sulfonyl)Imide brings together unique physical and chemical traits that keep researchers, engineers, and manufacturers coming back to it as a high-value ionic liquid. Known by its molecular formula C11H17F6N3O4S2, this compound falls in the realm of organonitrogen salts with sulfonyl imide anions. Its structure features a pyrrolidinium core substituted with an allyl group and a methyl group, paired with the large, hydrophobic bis(trifluoromethylsulfonyl)imide anion. This structure gives it a low melting point and high ionic mobility, helping it stand up in applications demanding stable, non-volatile, and non-flammable materials. The density sits near 1.4 g/cm3, reflecting a tightly packed molecular arrangement. You might see it as a colorless to pale yellow solid, sometimes appearing flake-like, crystalline, or as fine powder depending on the synthesis method and storage conditions. It dissolves well in polar solvents. The HS Code usually matches substances categorized as organic chemicals, specifically ionic liquids based on pyrrolidinium cations, aligning with code 2933.39 for trade and regulatory paperwork.
This ionic liquid doesn’t just carry theoretical appeal. Its basic profile—solid at room temperature, but often processed or handled as a viscous liquid at slightly elevated temperatures—makes it flexible for many lab environments. The bis(trifluoromethyl) sulfonyl imide anion gives the compound hydrophobicity and thermal stability. The liquid phase can serve as an electrolyte in batteries, supercapacitors, and electrochemical devices, benefiting from high ionic conductivity and broad electrochemical windows. This compound resists degradation in air and stays stable from acidic to weakly basic environments. The boiling point soars past 350°C, well above temperatures that send many organic chemicals to breakdown or decomposition. Its high density and ionic nature help separate it from simple organic solvents on both physical and regulatory grounds.
Raw material comes available in several formats: viscous oily liquid, crystalline solid, small pearls, fine powder, or flakes. Batch synthesis method, purification, and intended application usually direct which physical form shows up in the bottle. Powders give good dispersibility for composite manufacturing, whereas liquids or solutions often fill out the needs for electrochemical studies. Transparency matters, but color does not always signal purity; impurities can vary the color from clear to pale yellow. Solubility leans toward polar organic solvents, but water solubility stays limited—a core advantage in separation steps. High purity (over 99%) is routine, especially for use in sensitive chemical or electronic environments where contaminants can undermine final product reliability.
Years spent in chemical research make it clear how ionic liquids like this one push boundaries in next-generation devices. In batteries and supercapacitors, stable non-volatile electrolytes mean safer, longer-lasting storage devices. In pharmaceuticals, they offer new ways of dissolving and stabilizing otherwise unstable compounds. In catalysis, they unlock greener pathways by acting as reusable, recyclable solvents, cutting down waste and exposure to harsh reactions. Process engineers appreciate the variety of available forms—oily liquid, solid flakes, or pearlized granules—because processing needs flip depending on whether they build electrodes, run continuous flow setups, or study material compatibility.
Chemistry labs must keep safety front and center with this compound. Although N-Allyl-N-Methylpyrrolidinium Bis((Trifluoromethyl)Sulfonyl)Imide offers much lower vapor pressure and flammability than volatile organics, skin and eye contact may cause irritation and should be avoided with gloves and goggles. The presence of fluorinated sulfonyl imides signals an extra level of care, especially in waste handling and accidental release, since decomposition products under heat can release harmful gases like HF and SOx. Inhalation risks remain low unless dust or aerosols arise during powder handling, but it pays to keep good local ventilation. Safe storage means keeping the material in dry, sealed containers, protected from direct sunlight and reactive chemicals. Waste material disposal ties to national regulations for organic chemical waste, with no shortcuts for washing down lab drains. Long-term data on environmental persistence and toxicity remain under ongoing study, so responsible stewardship guides both research and industrial use. The chemical isn’t classified as explosive or acutely toxic under standard regulatory frameworks, but cumulative effects should steer users toward a precautionary mindset.
Working with N-Allyl-N-Methylpyrrolidinium Bis((Trifluoromethyl)Sulfonyl)Imide teaches the importance of understanding detailed physical properties and regulatory codes, not just chemical theory. Its structure and density open pathways that keep innovation moving forward in battery storage, catalysis, and separation science—offering practical, scalable answers to modern technology’s needs. At the same time, handling requirements, potential hazards, and environmental impact play a real role in shaping its place in labs and manufacturing. Rather than treat it as just another raw material, thoughtful users integrate its chemical strengths and safe-handling requirements into every step of research, scale-up, and production, turning a powerful molecule into a real-world asset for sustainable progress.
