Used as an ionic liquid in electrochemical applications such as batteries and supercapacitors due to its high ionic conductivity and wide electrochemical stability window. It serves as a solvent in organic synthesis, especially in reactions requiring non-volatile and thermally stable media. Commonly employed in green chemistry processes to replace volatile organic solvents, reducing environmental impact. Applied in separation processes, including extraction of metals and desulfurization of fuels. Also utilized in analytical chemistry as a buffer additive in capillary electrophoresis to improve separation efficiency.
