1-Hexyl-3-methylimidazolium Bis(trifluoromethanesulfonyl)imide TCI H1423

1-Hexyl-3-methylimidazolium Bis(trifluoromethanesulfonyl)imide is an ionic liquid — a salt composed of an imidazolium cation bearing a hexyl chain paired with the bis(trifluoromethanesulfonyl)imide anion — that remains liquid across the temperature range ordinarily encountered in laboratory work. Unlike conventional organic solvents, this material consists entirely of ions, which gives it a solvent environment fundamentally different from molecular media. In the laboratory it serves as a reaction medium, an extraction solvent, and an electrolyte for electrochemical experiments, and it is frequently selected in situations where conventional volatile solvents are considered inadequate for the work at hand.

The properties that make this ionic liquid a preferred choice begin with its extremely low vapour pressure, which means it is practically non-volatile under ordinary conditions. It offers a wide thermal and electrochemical stability window along with sufficient ionic conductivity that no supporting electrolyte salt needs to be added. The bis(trifluoromethanesulfonyl)imide anion is hydrophobic and strongly charge-delocalised, so this ionic liquid tends not to mix completely with water and instead forms two distinct phases, a behaviour that simplifies product separation. The hexyl chain length on the cation further raises the non-polar character of the liquid.

In Indonesian laboratories this ionic liquid is typically encountered in research and method-development settings rather than in routine bulk analysis. It is used where a non-volatile reaction medium is wanted, where a biphasic system with water is needed to recover a product, or where an electrochemical experiment calls for a conductive medium with a broad stability window. Because the material is used in relatively small volumes and its behaviour differs from familiar molecular solvents, it is generally handled by workers already familiar with ionic liquid systems.

• Reaction medium for organic synthesis — the fully ionic environment and negligible vapour pressure allow reactions to be run without solvent loss through evaporation, and the wide thermal stability window supports work above ambient temperature.
• Liquid-liquid extraction solvent — the hydrophobic bis(trifluoromethanesulfonyl)imide anion keeps the ionic liquid from mixing completely with water, forming a clean two-phase system that makes transfer and recovery of the target product straightforward.
• Electrolyte for electrochemical experiments — sufficient intrinsic ionic conductivity means measurements can be performed without adding a supporting electrolyte salt, while the broad electrochemical stability window widens the accessible potential range.
• Non-volatile replacement for conventional organic solvents — where a volatile solvent would evaporate during prolonged heating or open handling, this material remains in place, keeping the composition of the reaction mixture effectively constant throughout.
• Studies of solvation in non-polar ionic media — the hexyl chain on the imidazolium cation raises the non-polar character of the liquid, providing a solvent environment distinctly different from both water and ordinary molecular solvents.

Store the container tightly closed in a cool, dry place away from direct sunlight and heat sources, following the conditions given on the manufacturer's label. Use containers of a material compatible with ionic liquids and keep them sealed when not in use, since this material is hygroscopic in handling terms and picking up atmospheric moisture may alter its behaviour in both electrochemical and extraction work. Handle in a well-ventilated area or fume hood, wearing safety glasses, suitable gloves, and a laboratory coat. Avoid contact with skin and eyes, use clean and dry transfer equipment to prevent cross-contamination, and consult the manufacturer's safety data sheet before use and for disposal guidance.
