Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of certain rice field herbicides. Its structure allows for further functionalization to form active agrochemical ingredients that inhibit acetolactate synthase (ALS), an enzyme critical for plant amino acid biosynthesis. Due to its reactivity and selectivity, it plays an important role in constructing pyrimidine-based sulfonylurea compounds with high herbicidal activity and crop selectivity.
