Used as a Lewis acid catalyst in organic synthesis, particularly in Friedel-Crafts acylations and alkylations, where it promotes carbon-carbon bond formation under mild conditions. Effective in water-tolerant reactions, making it suitable for one-pot syntheses and green chemistry applications. Also employed in coupling reactions such as Diels-Alder and Michael additions due to its high catalytic activity and stability. Its non-hygroscopic nature compared to other metal triflates enhances handling and storage in industrial processes.
