Used as an ionic liquid solvent in chemical reactions, especially in catalysis and organic synthesis due to its high solvating power and thermal stability. Commonly employed in biomass processing to dissolve cellulose and lignin for biofuel production. Acts as a green solvent in place of volatile organic compounds, reducing environmental impact. Also applied in electrochemistry, such as in batteries and capacitors, where it enhances ion conductivity and device performance. Its low volatility and non-flammability make it suitable for industrial processes requiring safer solvents.
