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 formation of compounds that inhibit acetolactate synthase (ALS), an enzyme critical for plant amino acid biosynthesis. Due to its reactivity and functional groups, it allows for efficient coupling in multi-step syntheses of agrochemicals. It is valued in crop protection chemistry for contributing to selective weed control with low mammalian toxicity.
