Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of highly effective rice field herbicides. Its structure enables the development of compounds with high selectivity against broadleaf and sedge weeds while maintaining crop safety in paddy fields. The presence of reactive functional groups allows for further chemical modifications to enhance herbicidal activity, environmental stability, and absorption in target plants. It plays a critical role in agrochemical research and development for next-generation weed control solutions.
