Used as a key intermediate in the synthesis of agricultural herbicides, particularly in the production of highly effective rice herbicides. It plays a critical role in controlling broadleaf and grassy weeds by inhibiting acetolactate synthase (ALS), an enzyme essential for plant amino acid synthesis. Due to its selective action and high potency, formulations containing derivatives of this compound are favored for pre- and post-emergent weed control in paddy fields. Its chemical structure allows for easy modification to enhance herbicidal activity, selectivity, and environmental stability.
