1-Carboxymethyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide belongs to the family of ionic liquids, substances often prized for unique molecular architecture and remarkable physical properties. With a molecular formula of C9H11F6N3O7S2, this compound features an imidazolium cation modified with a carboxymethyl and a methyl group, counterbalanced by a bis(trifluoromethylsulfonyl)imide anion. Identifying the structure at the atomic level highlights the role electronegative fluorine atoms play, surrounded by sulfonyl groups, imparting thermal and chemical stability. The material appears in forms such as colorless to pale yellow liquid, but can also be solid, powder, or even crystalline depending on environmental conditions and purity.
Trade and regulatory compliance involves correctly assigning an HS Code. 1-Carboxymethyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide, as a specialty chemical, typically falls under HS Code 294200, categorizing organic compounds not otherwise specified. Specification sheets from manufacturers provide relevant information such as minimum purity levels, impurity profile, particle size (for flakes or powder), and acceptable moisture content. Density values tend to hover around 1.4-1.7 g/cm³ at room temperature, but can shift due to the compound’s hygroscopic nature. Known for high solubility in polar solvents and low volatility, these characteristics offer versatility for material scientists.
Depending on synthesis and storage, 1-Carboxymethyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide exists in several forms: crystalline solid, free-flowing powder, or viscous liquid. For industrial-scale users, physical form influences not just handling but also the ability to dose accurately and blend with other materials. Powdered or flake forms simplify bulk transport and long-term storage, as compared to pearls or liquid, which are quicker for in-line applications but may require additional containment and environmental controls. Under laboratory light and at typical room conditions, the compound maintains visual clarity and low odor, which reflects purity and minimal contamination.
Researchers appreciate the remarkable electrochemical stability window of this compound, especially useful as an electrolyte in energy storage devices. Low melting point, non-flammable nature, and negligible vapor pressure distinguish it from more hazardous volatile organic solvents. Laboratory testing has shown resistance to degradation even when exposed to strong acids or bases, owing to the robust C–N and S–N bonding within its molecular framework. As a raw material, the ionic liquid acts as a stabilizer, supporting cation exchange reactions, serving as a reaction medium for organometallic synthesis, and increasingly, as a starting material in advanced battery and capacitor development. Moisture absorption can slightly impact density and flow, so secure sealed packaging remains essential for preserving all performance properties.
Safety data indicates 1-Carboxymethyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide demands sensible handling like any laboratory-grade chemical. Direct contact with skin or inhalation of dust or vapor should be avoided. Proper personal protective equipment—gloves, goggles, lab coat—remains non-negotiable in industrial or research settings. Toxicological results suggest low oral and dermal toxicity, but chronic effects have not received exhaustive study, so conservative precaution makes sense. As a non-volatile compound, risk of fire or explosion under room conditions is minimal. Waste management teams should treat aqueous solutions or spill residues via absorption with inert material, then process for hazardous waste in accordance with local regulations since fluorinated sulfonyl groups resist breakdown and may persist in the environment.
The value of this ionic liquid stretches beyond conventional solvent use. As a conductive electrolyte in lithium-based batteries or electrode interface modifier, results show high ionic conductivity and wide operational thermal range. Laboratories performing materials science research often rely on it as a benchmark to screen new imidazolium derivatives, or as a reaction medium supporting catalyst performance. Its chemical robustness encourages adoption in pharmaceutical synthesis, biomaterials, and as an additive to enhance solubility of specific reactants. Feedback from academic and industrial chemists reveals consistent reproducibility and minimal side reactions even at elevated temperatures, a rare feat matched by very few other raw materials.
Any facility storing 1-Carboxymethyl-3-Methylimidazolium Bis(Trifluoromethylsulfonyl)Imide should prioritize airtight containers, shielded from humidity and intense sunlight. Flakes and powders require minimal agitation to avoid airborne dust; liquid and crystal forms benefit from inert gas blanketing during transfer. Facilities have had success with glass or HDPE storage tanks, which prevent contamination and preserve original product density specification. Regular rotational stock checks reduce the risk of inadvertent exposure or degradation. Material safety teams recommend document retention for all procurement and usage records, as traceability can become crucial for users operating in regulated pharmaceutical, energy, or electronics sectors.
Production relies on reliable sources for both the imidazolium precursor and the bis(trifluoromethylsulfonyl)imide anion, with supply chain transparency improving as global standards mature. Large-scale facilities partner with specialty chemical producers to secure unbroken availability of raw materials, often entering long-term contracts that guarantee specified purity levels and shipment packaging. In practice, every batch receives comprehensive release testing, including density, melting point, and checks for trace metals or halides, as contaminant levels must stay well below application-specific thresholds. The move toward more sustainable synthetic routes—minimizing waste and avoiding toxic reagents—follows industry-wide pushes for greener chemistry.
