Used as an ionic liquid catalyst in organic synthesis, particularly in Friedel-Crafts alkylation and acylation reactions due to its strong Lewis acidity. It facilitates high selectivity and reaction efficiency under mild conditions. Also employed in electrochemical applications, such as battery electrolytes and electrodeposition of aluminum, thanks to its wide electrochemical window and ionic conductivity. Its low volatility makes it suitable for green chemistry processes where traditional volatile solvents are undesirable.
