Used as a key intermediate in the synthesis of sulfonylurea herbicides, particularly in the production of certain broad-spectrum agricultural herbicides that inhibit acetolactate synthase (ALS) in plants. Its structure allows for efficient coupling with heterocyclic amines to form active herbicidal compounds effective against a wide range of weeds in crop protection. Commonly employed in the development of post-emergence herbicides for use in cereals and other selective crops. Also utilized in research for designing new sulfonylurea derivatives with improved environmental and efficacy profiles.
