Widely used as an ionic liquid in various chemical reactions due to its excellent solvation properties and thermal stability. It serves as a catalyst or solvent in organic synthesis, particularly in reactions like esterification, alkylation, and polymerization. Its application extends to electrochemical systems, where it enhances conductivity and stability in batteries and supercapacitors. Additionally, it is utilized in the extraction and separation processes, such as in the removal of heavy metals or the purification of biomolecules. Its role in green chemistry is notable, as it reduces the need for volatile organic solvents.
