Widely used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of sulfa drugs and other bioactive molecules. Its fluorinated aromatic structure enhances the metabolic stability and membrane permeability of final drug compounds. Commonly employed in the preparation of sulfonamide derivatives, which are key structural motifs in various therapeutic agents, including anti-inflammatory, antimicrobial, and antidiabetic drugs. Also utilized in agrochemical synthesis for developing herbicides and pesticides due to its reactivity and ability to introduce sulfonyl groups into complex molecules. Preferred in organic synthesis for its selective reactivity with amines and alcohols under mild conditions.
