Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of anti-inflammatory and central nervous system agents. Its sulfonyl chloride group allows for easy conversion to sulfonamides, which are common motifs in drug molecules. Also employed in agrochemical synthesis for creating herbicides and plant growth regulators. The fluorine atom enhances binding selectivity and metabolic stability in final active compounds. Commonly utilized in research settings for structure-activity relationship (SAR) studies due to its reactive handles for derivatization.
