Used as an ionic liquid in various chemical processes due to its low volatility and high thermal stability. Commonly serves as a solvent in organic synthesis, including Heck and Suzuki coupling reactions, hydrogenation, polymerization, and transesterification for biodiesel production, where it enhances reaction efficiency and catalyst recyclability. Applied in electrochemistry as an electrolyte in batteries and supercapacitors because of its good ionic conductivity and wide electrochemical window. Also utilized in separation processes, such as extraction of metals or desulfurization of fuels. Its non-flammable nature and ability to dissolve a wide range of compounds make it suitable for green chemistry applications.
