Used as an ionic liquid in electrochemical applications, particularly in batteries and capacitors due to its high thermal stability and wide electrochemical window. It serves as a solvent or electrolyte component in fuel cells and dye-sensitized solar cells, enhancing ion conductivity and device efficiency. Also employed in separation processes, such as extraction of organic compounds or metal ions, thanks to its low volatility and tunable solvation properties, and as a stationary phase in gas chromatography for efficient separation of low to medium polarity compounds. Additionally, it finds use in green chemistry applications as a reusable reaction medium for catalytic reactions, including coupling and polymerization reactions.
