Widely used as an ionic liquid in various electrochemical applications, it serves as an electrolyte in batteries and supercapacitors due to its high ionic conductivity and thermal stability. It is also employed in catalysis, particularly in organic synthesis, where it enhances reaction rates and selectivity. Additionally, it is utilized in separation processes, such as liquid-liquid extraction, for isolating specific compounds from mixtures. Its non-volatile and non-flammable nature makes it a safer alternative to traditional solvents in industrial applications.
