Used as an intermediate in the synthesis of sulfonylurea herbicides. It plays a key role in agrochemical manufacturing, particularly in creating compounds that inhibit plant growth by targeting acetolactate synthase (ALS) enzymes. Its reactive sulfonyl chloride group allows for easy coupling with amines to form sulfonylurea linkages, which are essential for herbicidal activity. Commonly applied in the development of selective broadleaf weed control agents in crops such as rice, wheat, and corn.
