Used primarily as an ionic liquid in electrochemical applications, such as in batteries and supercapacitors, due to its high thermal stability and wide electrochemical window. It serves as a solvent and electrolyte component in lithium-ion and dye-sensitized solar cells, enhancing ion conductivity and device efficiency. Its low volatility and good solvating properties make it suitable for green chemistry processes and catalytic reactions. Also employed in separation processes and as a medium in organic synthesis where stable, non-aqueous environments are required.
