Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high ionic conductivity and wide electrochemical stability window. It serves as a green solvent in organic synthesis, facilitating reactions like hydrogenation, coupling, and polymerization with improved yields and recyclability. Also employed in separation processes, including CO₂ capture and extraction of metals, thanks to its low volatility and tunable solvation properties. Its thermal stability makes it suitable for use in high-temperature reactions and analytical techniques such as gas chromatography.
