Cas no 81123-38-8 (5-hydroxy Chlorosulfuron)

5-Hydroxy Chlorosulfuron is a sulfonylurea herbicide known for its selective post-emergence activity against broadleaf weeds and some grass species in cereal crops. Its mode of action involves inhibition of acetolactate synthase (ALS), disrupting branched-chain amino acid synthesis in target plants. The hydroxyl group at the 5-position enhances its metabolic stability and bioavailability, contributing to prolonged residual activity at low application rates. This compound exhibits high crop selectivity in wheat, barley, and other cereals, with minimal soil persistence under appropriate conditions. Its efficacy is maintained across a range of soil types and pH levels, though performance may vary with organic matter content. Proper application timing is critical to maximize weed control while minimizing crop phytotoxicity.
