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 and nitrile groups allow for further chemical modifications, making it valuable in building complex herbicidal molecules. Commonly employed in the production of rice and wheat field herbicides due to its selectivity and efficiency in controlling broadleaf weeds.
