Used primarily as a key intermediate in the synthesis of pharmaceuticals and agrochemicals. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for constructing sulfonamide and sulfonate ester derivatives. Commonly employed in the development of bioactive molecules, including antifungal, antibacterial, and anti-inflammatory agents. The presence of bromo and trifluoromethyl groups allows for further functionalization via cross-coupling reactions, enhancing its utility in medicinal chemistry and drug discovery. Also applied in the preparation of specialty polymers and functional materials where halogenated and fluorinated building blocks are required.
