Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the development of rice field herbicides. Its structure allows for efficient coupling reactions in agrochemical pathways, enhancing selectivity and activity against broadleaf weeds. Also employed in the preparation of pyrimidine-based fungicides and plant growth regulators. Its sulfonyl and ester functionalities make it suitable for further functionalization in heterocyclic chemistry for crop protection agents.
