Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs. Its structure allows for the introduction of sulfonyl chloride functional groups that react readily with amines to form sulfonamides, which are common motifs in antimicrobial and anti-inflammatory agents. Also employed in agrochemical synthesis for creating herbicides and fungicides due to the stability and bioavailability imparted by the trifluoromethyl and phenoxy groups. Its reactivity makes it valuable in organic synthesis for building complex molecules in medicinal chemistry research.
