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. Employed in electrochemical applications such as electrolytes for lithium-ion and zinc-based batteries, where it enhances ionic conductivity and improves electrode stability. Serves as a dopant in conductive polymers to increase electrical conductivity and environmental stability. Applied in ionic liquids to create low-melting, thermally stable systems suitable for green chemistry processes. Also utilized in polymerization reactions as a co-catalyst, promoting controlled polymer architectures with narrow molecular weight distributions.
