Description

1‐Methyl‐3‐Pentylimidazolium Bis(Trifluoromethylsulfonyl)Imide is a high-purity ionic liquid belonging to the [C1C5Im][NTf2] family. This compound matters for its exceptional combination of low viscosity, high thermal stability, and wide electrochemical window, making it a superior solvent and electrolyte medium. It is primarily needed by researchers and manufacturers in the fields of electrochemistry, advanced material synthesis, and green chemistry as a non-volatile, tunable reaction medium.

Application

• Electrolyte Component for lithium-ion batteries, supercapacitors, and dye-sensitized solar cells (DSSCs).
• Green Solvent Medium for catalysis, organic synthesis, and polymerization reactions, replacing volatile organic compounds (VOCs).
• Gas Separation & Capture as a functional fluid in supported ionic liquid membranes (SILMs) for CO2 absorption.
• Lubricant & Additive in advanced tribological systems for its thermal stability and low vapor pressure.
• Analytical Chemistry as a stationary phase modifier in gas chromatography (GC) and capillary electrophoresis (CE).
• Material Processing for the dissolution and processing of biopolymers like cellulose or synthetic polymers.
