Used primarily as an intermediate in the synthesis of sulfonylurea herbicides. It plays a key role in agricultural chemistry, enabling the production of highly effective weed control agents. Its reactive sulfonyl chloride group allows for easy coupling with urea derivatives, forming herbicidally active compounds that inhibit plant acetolactate synthase (ALS), disrupting amino acid synthesis in target weeds. Due to its reactivity and specificity, it is valued in the development of selective herbicides for use in crops such as rice, wheat, and corn. Handling requires care due to its moisture sensitivity and potential to release corrosive fumes.
