Used primarily as a key intermediate in the synthesis of agrochemicals and pharmaceuticals, particularly in the production of sulfonylurea herbicides. Its structure allows for efficient coupling reactions, making it valuable in creating compounds with high biological activity. It is also employed in organic synthesis to introduce the sulfonyl chloride functional group, enabling further derivatization in drug development and chemical research. Due to its reactivity, it facilitates the formation of sulfonamides, which are common motifs in bioactive molecules.
