Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of sulfonyl groups into complex molecules, making it valuable in the development of active ingredients in crop protection agents and medicinal compounds. It is especially useful in the preparation of sulfonamide derivatives, which are common structural motifs in drugs targeting inflammation, infections, and central nervous system disorders. The compound's halogen and trifluoromethyl functionalities enable further chemical modifications, enhancing its utility in structure-activity relationship studies during drug discovery.
