Used primarily as an ionic liquid in electrochemical applications due to its high thermal stability and low volatility. Commonly employed as an electrolyte in lithium-ion batteries and supercapacitors, where it enhances ion conductivity and improves device safety by reducing flammability. Its wide electrochemical window makes it suitable for use in dye-sensitized solar cells and fuel cells. Also utilized as a green solvent in organic synthesis, facilitating reactions such as palladium-catalyzed cross-couplings without the need for volatile organic solvents. Stable under both acidic and basic conditions, it supports biphasic catalytic systems and enables easy product separation.
