Used as an ionic liquid in green chemistry applications, particularly as a catalyst or solvent in organic synthesis due to its low volatility and high thermal stability. It facilitates reactions such as esterification, transesterification, and CO2 capture, offering an environmentally friendly alternative to traditional volatile solvents. Its non-flammable nature and ability to be recycled make it suitable for sustainable industrial processes. Also explored in electrochemical applications like batteries and fuel cells where ionic conductivity and stability are essential.
