Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) with enhanced biological activity. Its trifluoromethylthio group is valuable for improving the metabolic stability and lipophilicity of drug molecules.

Applied in agrochemical research for creating advanced pesticides and herbicides, where the trifluoromethylthio moiety contributes to increased efficacy and resistance to degradation.

Employed in organic synthesis for the preparation of specialty chemicals, including dyes, pigments, and polymers, where it acts as a building block for introducing functional groups.

Utilized in material science for modifying surfaces or creating coatings with specific properties, such as water repellency or chemical resistance.

Its reactivity as an acyl chloride makes it a versatile reagent for coupling reactions, enabling the formation of amides, esters, and other derivatives in synthetic chemistry.
