Used primarily as an intermediate in the synthesis of sulfonylurea herbicides and other agrochemicals. Its reactivity allows for the introduction of sulfonyl groups into organic molecules, particularly by reacting with urea or derivatives to form sulfonylureas with specific activity at low application rates, aiding weed control in crops such as corn, soybeans, and certain vegetables while reducing production costs and environmental impact. Also employed in the preparation of sulfonamides for pharmaceuticals and in research settings for modifying bioactive compounds to enhance stability and binding affinity.
