Used as a highly effective catalyst in organic synthesis, particularly in Friedel-Crafts acylation and alkylation reactions due to its strong Lewis acidity and moisture tolerance. Commonly employed in the production of fine chemicals, pharmaceuticals, and agrochemicals where high selectivity and yield are required. Also utilized as an electrolyte component in lithium-ion and zinc-based batteries, enhancing ionic conductivity and electrochemical stability. Its non-coordinating anions make it suitable for promoting cationic polymerization and other ionic reactions. Additionally, applied in ionic liquids to improve thermal stability and catalytic performance in industrial processes.
