Used as an ionic liquid in various industrial and research applications. It serves as a solvent in chemical reactions, particularly in catalysis and organic synthesis, due to its stability and low volatility. It is also employed in electrochemistry, including batteries and capacitors, because of its high ionic conductivity and wide electrochemical window. Additionally, it is utilized in separation processes, such as liquid-liquid extraction, for its ability to selectively dissolve specific compounds. Its thermal stability makes it suitable for high-temperature applications.
