Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and insecticides. Its sulfonyl chloride group readily reacts with amines and alcohols, making it valuable for introducing the 6-(trifluoromethyl)pyridine moiety into larger molecules. This structural fragment is known to enhance metabolic stability and binding affinity in bioactive compounds. Commonly employed in the preparation of sulfonamide derivatives with biological activity. Also utilized in research settings for the design of novel catalysts and functional materials.
