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, enhancing efficiency and performance. Also employed as a solvent or catalyst in organic synthesis, facilitating reactions like esterification and polymerization. Its low volatility and non-flammability make it suitable for green chemistry processes. Additionally, it is utilized in gas separation technologies and as a lubricant additive to reduce friction and wear.
