Used as an ionic liquid in electrochemical applications such as batteries and fuel cells 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 easy product separation and recyclability. Applied in separation processes, including gas absorption and liquid-liquid extraction, especially for removing sulfur compounds from fuels. Its thermal stability and low volatility make it suitable for use in high-temperature reactions and as a medium in catalytic systems. Also explored in analytical chemistry for use in chromatography and as a matrix in mass spectrometry.
