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 because of its low vapor pressure and reusability. Applied in separation processes, including CO₂ capture and extraction of metals, thanks to its tunable solvation properties. Also utilized in analytical chemistry as a buffer additive in capillary electrophoresis to improve separation efficiency.
