Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of herbicides and fungicides. Its reactive sulfonyl chloride group enables easy attachment to other molecules, making it valuable in creating sulfonamide derivatives. Commonly employed in the development of sulfonylurea herbicides, which are effective at low application rates and offer high selectivity between crops and weeds. Also utilized in medicinal chemistry for constructing bioactive molecules due to its ability to enhance metabolic stability and binding affinity.
