Used as an ionic liquid in catalysis and organic synthesis due to its high thermal stability and low vapor pressure. Commonly serves as a green solvent in reactions such as Heck coupling, Diels-Alder, and hydrogenation, where it enhances reaction rates and selectivity. Also applied in electrochemistry, including as an electrolyte in batteries and supercapacitors, owing to its wide electrochemical window and good ionic conductivity. Its non-volatile nature makes it suitable for use in separation processes and extraction of compounds, including metal ions and biomolecules. Additionally, employed in analytical chemistry for matrix-assisted laser desorption/ionization (MALDI) mass spectrometry and as a background electrolyte in capillary electrophoresis.
