Description

Metosulam is a selective systemic herbicide belonging to the sulfonamide chemical class, widely recognized for its post-emergence activity against broadleaf weeds. Its primary value lies in providing effective and long-lasting control in key cereal crops, offering growers a reliable solution for integrated weed management. This product is essential for agricultural professionals and formulators in the global agrochemical industry seeking high-purity active ingredients for crop protection solutions. Metosulam CAS NO 139528-85-1 is a critical component in modern herbicide formulations.

Application

• Selective Herbicide Formulations: Primary use as the active ingredient in post-emergence herbicide products for cereals like wheat, barley, and rye.
• Broadleaf Weed Control: Effective against a wide spectrum of problematic broadleaf weeds, including chickweed, mayweed, and cleavers.
• Agrochemical Intermediates: Serves as a key intermediate in the synthesis of more complex crop protection agents and specialty chemicals.
• Research & Development: Used in agricultural R&D for studying weed resistance mechanisms and developing new herbicide technologies.
• Technical Material for Formulators: Supplied as a high-purity technical material for manufacturers to produce commercial-grade emulsifiable concentrates (EC) or suspension concentrates (SC).
• Integrated Pest Management (IPM): A tool in IPM programs due to its selectivity, helping to manage weed populations while preserving crop health and yield.

Quality Control

Our Metosulam is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Every lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to meet exacting technical-grade specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your specifications and industry standards.

Storage

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