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. Applied in separation processes, including gas absorption and extraction, thanks to its tunable solvation properties. Also utilized in analytical chemistry as a matrix in mass spectrometry and as a background electrolyte in capillary electrophoresis.
