Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of sulfonamide-based drugs. Its fluorinated pyridine structure enhances binding selectivity and metabolic stability in active compounds. Commonly employed in the preparation of kinase inhibitors and other bioactive molecules where the sulfonyl chloride group facilitates attachment to amines or alcohols. Also utilized in agrochemical research for designing novel pesticides with improved efficacy and environmental profile. The compound’s reactivity allows for efficient derivatization in multi-step organic syntheses.
