Used as an ionic liquid in electrochemical applications, particularly in lithium-ion batteries, fuel cells, and supercapacitors due to its high ionic conductivity and thermal stability. Enhances electrolyte performance by improving ion transport and widening the electrochemical stability window. Also employed as a solvent or catalyst support in organic synthesis, such as Friedel-Crafts reactions, esterification, or biomass conversion, where low volatility, high polarity, and reusability without significant degradation are advantageous. Its strong solvating ability makes it suitable for CO2 capture and separation processes. Additionally, applied in analytical chemistry as a buffer component in capillary electrophoresis for improved separation of ionic compounds.
