Used as an ionic liquid in various industrial and research applications, particularly in electrochemical systems such as batteries and fuel cells due to its high ionic conductivity and stability. It is also employed as a solvent in chemical reactions, especially in catalysis and organic synthesis, where it enhances reaction rates and selectivity. Additionally, it finds use in the extraction and separation processes, particularly for biomolecules and metal ions, owing to its tunable properties and ability to dissolve a wide range of substances. Its low volatility and non-flammability make it a safer alternative to traditional organic solvents in many applications.
