Used as an ionic liquid in electrochemical applications, particularly in batteries and capacitors due to its good ionic conductivity and thermal stability. It serves as a solvent or electrolyte component in organic synthesis and catalysis, enhancing reaction efficiency under mild conditions. Also explored in separation processes, such as extraction of metals or desulfurization of fuels, thanks to its tunable solvation properties. Its low volatility makes it suitable for use in environmentally safer industrial processes.
