Widely used as an ionic liquid in electrochemical applications, particularly in batteries and supercapacitors, due to its high ionic conductivity and thermal stability. It serves as an electrolyte in dye-sensitized solar cells (DSSCs) to enhance efficiency and performance. Also employed as a solvent or catalyst in organic synthesis, especially in reactions requiring a non-volatile and recyclable medium. Its hydrophobic nature makes it suitable for extraction processes, such as separating metal ions or organic compounds from aqueous solutions. Additionally, it is used in lubrication to reduce friction and wear in mechanical systems.
