Used as a key intermediate in the synthesis of agricultural chemicals, particularly herbicides and plant growth regulators. Its structure allows for the development of compounds with selective activity against broadleaf weeds. Commonly employed in the production of sulfonylurea herbicides, where it contributes to the inhibition of acetolactate synthase (ALS), an enzyme critical for amino acid synthesis in plants. Due to its chloro and amino functional groups, it readily undergoes substitution and coupling reactions, making it valuable in agrochemical research and development. Also utilized in the preparation of novel picolinamide-based compounds with enhanced crop selectivity and environmental stability.
