Used as an ionic liquid solvent in chemical reactions, particularly in catalysis and organic synthesis due to its ability to dissolve a wide range of organic and inorganic compounds. Commonly applied in biomass processing for dissolving cellulose and lignin, enabling biofuel production. Employed in electrochemistry as a conductive medium in batteries and supercapacitors. Also utilized in separation processes, such as extraction of metals or removal of sulfur from fuels. Its low volatility and high thermal stability make it suitable for green chemistry applications where traditional volatile solvents are undesirable.
