Used as a solvent in various chemical reactions, particularly in catalysis and organic synthesis, due to its ionic liquid properties. It is effective in facilitating reactions like Diels-Alder, Friedel-Crafts, and hydrogenation processes.

Applied in electrochemical applications, such as electrolytes in batteries and supercapacitors, owing to its high ionic conductivity and stability.

Utilized in separation processes, including extraction of metal ions and purification of biomolecules, because of its ability to selectively dissolve specific compounds.

Employed in biomass processing, where it helps break down cellulose and lignin, making it valuable in biofuel production.

Also used in gas absorption, particularly for capturing CO2, due to its ability to dissolve gases efficiently.

Its low volatility and thermal stability make it suitable for high-temperature industrial applications.
