1. Organic Synthesis Catalysts
As a strong acid catalyst, it is widely used in esterification, acylation, Friedel-Crafts alkylation/acylation, Michael addition, Diels-Alder cycloaddition, and other reactions, effectively increasing reaction rate and efficiency.

2. Polymer Chemistry
As an initiator for cationic polymerization reactions, it is used to catalyze the polymerization of monomers such as olefins, epoxides, and vinyl ethers, enabling the preparation of high-molecular-weight polymers with controlled structures.

3. Peptide and Protein Chemistry
In solid-phase peptide synthesis, it serves as a key cleavage and deprotection agent, efficiently cleaving the synthesized peptide chain from the solid support.

4. Pharmaceutical and Fine Chemical Synthesis
Used in the synthesis of various key substances, such as nucleosides, antibiotics, steroids, vitamins, proteins, glycosides, and other pharmaceutical intermediates and active ingredients.

5.材料科学
Used in the synthesis of organic-inorganic hybrid materials, functional surfaces, and for silicone rubber modification.

6. Preparation of Highly Reactive Derivatives
Used as a raw material for the preparation of trifluoromethanesulfonic anhydride, trifluoromethanesulfonate esters, etc. Trifluoromethanesulfonate esters are highly reactive intermediates in organic synthesis, with reactivity far exceeding that of similar compounds.
