Used as an intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the development of herbicides and plant growth regulators. Its sulfonyl chloride group enables easy derivatization to sulfonamides or sulfonate esters, making it valuable in creating biologically active compounds. Commonly employed in the production of sulfonylurea herbicides, which are known for their high potency and selectivity in weed control. Also utilized in medicinal chemistry for constructing nitrogen-containing heterocyclic systems with potential biological activity.
