Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs with antimicrobial and anti-inflammatory properties. It serves as a building block in medicinal chemistry due to the electron-withdrawing trifluoromethoxy group enhancing metabolic stability and membrane permeability. Also employed in the preparation of carbonic anhydrase inhibitors, which are relevant in treating glaucoma and certain cancers. Its structure allows for easy functionalization, making it valuable in drug discovery and agrochemical research.
