Used as an ionic liquid in electrochemical applications such as lithium-ion batteries and supercapacitors due to its high thermal stability and wide electrochemical window. Its low volatility and good solvating properties make it suitable as a solvent in organic synthesis and catalysis. Also employed in separation processes and as a medium for gas absorption, particularly for CO₂ capture. Commonly found in studies involving green chemistry where non-aqueous, non-volatile reaction media are required.
