Used as an ionic liquid in electrochemical applications, particularly in capacitors and batteries, due to its high ionic conductivity and stability. It serves as a solvent or electrolyte in various chemical reactions, including catalysis and organic synthesis, where it enhances reaction efficiency and selectivity. Additionally, it is employed in separation processes, such as liquid-liquid extraction, for its ability to dissolve a wide range of substances. Its thermal stability makes it suitable for high-temperature applications in industrial processes, as well as in advanced materials research like nanotechnology and specialty polymers.
