Used as an ionic liquid in green chemistry applications, particularly as a solvent in organic synthesis due to its low volatility and high thermal stability. Facilitates reactions such as alkylations, esterifications, and polymerizations by improving yield and selectivity. Employed in electrochemical systems like batteries and capacitors because of its good ionic conductivity. Also applied in separation processes, including desulfurization of fuels and extraction of biomolecules, thanks to its tunable solvation properties. Its non-volatile nature makes it suitable for use in environmentally friendly processes where traditional volatile solvents are undesirable.
