Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of highly effective rice field herbicides. Its structure enables selective weed control by inhibiting acetolactate synthase (ALS) enzyme in unwanted plants, leading to disruption of branched-chain amino acid synthesis. It is valued for its role in developing herbicides with low application rates, high crop selectivity, and favorable environmental profile. Commonly employed in formulations targeting broadleaf and sedge-type weeds in paddy rice cultivation.
