Description

Bensulfuron Methyl CAS NO 83055-99-6 is a selective, systemic sulfonylurea herbicide known for its high activity at low application rates. This compound is critical for providing effective, long-lasting control of a broad spectrum of broadleaf weeds and sedges in key agricultural systems. It is an essential raw material for agrochemical manufacturers and formulators serving the global rice cultivation and aquatic weed management markets.

Application

• Primary Use in Rice Paddies: Selective post-emergence control of annual and perennial broadleaf weeds and sedges in transplanted and direct-seeded rice.
• Aquatic Weed Management: Used in the formulation of herbicides for managing unwanted vegetation in irrigation channels, ponds, and other slow-moving water bodies.
• Agrochemical Formulation: A key active ingredient in the production of wettable powders (WP), water-dispersible granules (WG), and other commercial herbicide formulations.
• Research & Development: Serves as a high-purity reference standard and intermediate in agricultural chemical research for developing new weed control solutions.

Quality Control

Our Bensulfuron Methyl is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, to ensure it meets the high-purity standards required for agrochemical synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and performance.
