Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of sulfa-based active ingredients. Its reactive sulfonyl chloride group enables easy attachment to amines or alcohols, forming sulfonamides or sulfonate esters, which are key structural motifs in herbicides and antimicrobial agents. Commonly employed in the production of sulfonylurea herbicides due to its ability to link aromatic systems with nitrogen-containing heterocycles, enhancing selectivity and potency against broadleaf weeds. Also utilized in medicinal chemistry for constructing enzyme inhibitors where the chloro and fluoro substituents influence electron distribution and binding affinity.
