Used as a versatile reagent in organic synthesis, particularly in trifluoromethylation and imidation reactions. It serves as a source of the trifluoromethanesulfonyl (triflyl) group, enabling the introduction of electron-withdrawing moieties to modify the stability and reactivity of organic compounds. Commonly applied in the preparation of sulfonamides and in catalytic transformations involving transition metals. Its strong electrophilic character makes it useful for generating reactive intermediates in fluorinated compound synthesis. Also employed in the development of pharmaceuticals and agrochemicals where fluorine-containing groups enhance metabolic stability and bioavailability.
