Description

Chlorsulfuron-5-Hydroxy is a key chemical intermediate and metabolite of the sulfonylurea herbicide chlorsulfuron. This compound is of significant interest for research and development in the agrochemical sector, particularly for studies on herbicide metabolism, environmental fate, and the synthesis of novel crop protection agents. It serves as a critical building block for analytical chemists, R&D scientists, and manufacturers focused on developing or monitoring advanced herbicide formulations and their breakdown pathways.

Application

• Agrochemical Research & Development: Primary use as a reference standard and intermediate in the synthesis and study of sulfonylurea herbicides.
• Metabolite Analysis: Essential for environmental and biological fate studies, used to track and quantify the degradation products of chlorsulfuron in soil and water.
• Analytical Standard: Serves as a high-purity certified reference material (CRM) for calibration in HPLC, LC-MS, and GC-MS methods in analytical laboratories.
• Chemical Synthesis: Utilized as a specialized precursor for creating novel derivatives with potential modified biological activity or improved properties.
• Quality Control: Employed by manufacturers to verify the purity and composition of technical-grade chlorsulfuron and its formulated products.
