Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to high thermal stability and ionic conductivity. Serves as a green solvent in organic synthesis, facilitating reactions like hydrogenation and coupling without volatile organic solvents. Applied in separation processes, including extraction of metals and desulfurization of fuels. Its low volatility and tunable polarity make it suitable for use in analytical techniques such as gas chromatography and mass spectrometry. Also investigated in catalysis, where it acts as both solvent and catalyst support, enhancing reaction efficiency and recyclability.
