Used as a selective reagent for the trifluoromethylation of aromatic compounds, particularly in late-stage functionalization of pharmaceuticals. It enables the introduction of the trifluoromethyl group under mild conditions, enhancing metabolic stability and lipophilicity in drug molecules. Commonly applied in the synthesis of bioactive compounds and agrochemicals where CF3 incorporation improves efficacy and resistance to degradation. Also serves as a photoredox catalyst in radical reactions when activated by visible light, supporting sustainable synthetic methods.
