Description

Metosulam-5-Hydroxy is a key chemical intermediate and metabolite of the selective herbicide Metosulam. This compound is crucial for research and development in the agrochemical sector, particularly in the study of herbicide metabolism, environmental fate, and the synthesis of analytical standards. It serves the needs of agrochemical manufacturers, analytical laboratories, and research institutions focused on crop protection science and regulatory compliance.

Application

• Agrochemical Research & Development: Primary use as a reference standard and metabolite in the study of Metosulam's mode of action, degradation pathways, and environmental impact.
• Analytical Standard: Critical for developing and validating HPLC, LC-MS, or GC-MS methods for the quantification of Metosulam and its residues in crops, soil, and water.
• Metabolite Synthesis: Serves as a key building block or precursor for the synthesis of other related metabolites or labeled compounds for tracer studies.
• Regulatory Compliance & Safety Testing: Essential for conducting toxicological studies and preparing regulatory dossiers required for product registration and safety assessments.
• Quality Control: Used as an impurity standard or system suitability check in the quality control of technical-grade Metosulam or its formulated products.

Quality Control

Our Metosulam-5-Hydroxy is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the high standards required for research and analytical applications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. Keep away from incompatible materials.
