Used as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and fungicides. Its sulfonyl chloride group readily reacts with nucleophiles, enabling the formation of sulfonamides and sulfonate esters that are important in bioactive molecule design. Commonly employed in medicinal chemistry for constructing kinase inhibitors and other targeted therapies. Also utilized in the preparation of pyrazole-based compounds with potential antimicrobial and anti-inflammatory activities.
