Description

Trifluoromethanesulfinic Acid (CAS No. 34642-42-7) is a highly specialized fluorinated sulfinic acid with the molecular formula CHF₃O₂S. This organosulfur compound is widely utilized in advanced synthetic chemistry and materials science due to its strong electron-withdrawing trifluoromethyl group and reactive sulfinic acid functionality. The product is supplied as a high-purity reagent, rigorously tested to meet the stringent requirements of pharmaceutical, agrochemical, and specialty chemical research. Its unique properties make it an excellent intermediate for nucleophilic trifluoromethylation reactions, ligand synthesis, and as a precursor for sulfonyl derivatives. Proper handling under inert conditions is recommended due to its sensitivity to moisture and oxidation.

Application

Trifluoromethanesulfinic acid serves as a key building block in the synthesis of trifluoromethylated compounds, which are critical in drug discovery and agrochemical development. It is employed as a nucleophilic trifluoromethylating agent in organic transformations, enabling the introduction of the CF₃ group into complex molecules. Researchers also utilize it to prepare sulfonamide derivatives and as a ligand modifier in catalytic systems. Its applications extend to materials science for surface modification and functional polymer synthesis.
