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 stability. It is also employed in catalysis, particularly in organic synthesis, where it facilitates reactions under mild conditions. Additionally, it is utilized in separation processes, such as extractive distillation and liquid-liquid extraction, owing to its ability to selectively dissolve certain compounds. Its thermal stability makes it suitable for high-temperature applications, including in lubricants and heat transfer fluids.
