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 bromine allows for further functionalization via cross-coupling reactions such as Suzuki or Heck reactions, enabling rapid diversification in medicinal chemistry research. Also utilized in the preparation of specialty chemicals requiring high lipophilicity and metabolic stability, due to the trifluoromethoxy moiety.
