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 for organic reactions, including alkylation, acylation, and other processes requiring non-volatile and thermally stable media that are not highly moisture-sensitive. Commonly employed in green chemistry processes because of its low vapor pressure and reusability.

Applied in separation processes, including CO₂ capture, metal extraction, and chromatography (especially in ionic liquid phases for separating polar compounds), thanks to its tunable solvation properties.

Also utilized in fuel cells as a component of proton-conducting membranes when doped with acids. In materials research, it acts as a medium for synthesizing nanomaterials or conductive polymers, enabling good control over crystal growth and uniform structures.
