Used as a Lewis acid catalyst in organic synthesis, particularly in Friedel-Crafts acylations and alkylations, enabling efficient carbon-carbon bond formation. Effective in promoting glycosylation reactions for carbohydrate chemistry due to its moisture tolerance and stability. Employed in coupling reactions such as Diels-Alder and Michael additions, offering high yields and selectivity. Also utilized in electrochemical applications and as a catalyst in esterification and transesterification processes for biodiesel production. Its non-corrosive nature and reusability make it suitable for green chemistry applications.
