Used as an ionic liquid in electrochemical applications such as batteries and capacitors due to its high thermal stability and ionic conductivity. Serves as a green solvent in organic synthesis, facilitating reactions like hydrogenation, coupling, and polymerization without the need for volatile organic solvents. Employed in separation processes, including extraction of metals and desulfurization of fuels, thanks to its ability to selectively dissolve compounds. Also utilized in analytical chemistry as a matrix or electrolyte in sensors and spectrometry due to its low vapor pressure and wide electrochemical window.
