Used as an ionic liquid in various chemical reactions and processes, particularly in catalysis and organic synthesis. It serves as a solvent or catalyst in reactions like Diels-Alder, Friedel-Crafts, and polymerization due to its stability and low volatility. It is also employed in electrochemical applications, such as electrolytes in batteries and supercapacitors, owing to its high ionic conductivity and thermal stability. Additionally, it is utilized in separation processes and as a medium for nanoparticle synthesis. Its non-flammable and non-corrosive nature makes it a safer alternative to traditional solvents in industrial applications.
