Description

Orthosulfamuron is a selective, systemic sulfonylurea herbicide known for its high efficacy at low application rates. This compound is critical for modern agricultural practices, offering targeted weed control to protect crop yield and quality. It is primarily needed by agrochemical formulators and agricultural producers for use in rice cultivation and other key crops.

Application

• Pre- and post-emergence control of broadleaf weeds and sedges in rice paddies.
• Key component in the formulation of selective herbicide products for cereal crops.
• Used in integrated weed management (IWM) programs to combat herbicide-resistant weed species.
• Applied in agricultural research and development for new herbicide mixture formulations.
• Active ingredient in professional turf management products for specific weed spectra.
• Utilized in the synthesis of advanced agrochemical intermediates and analogs.

Quality Control

Our Orthosulfamuron is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for agrochemical formulation. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and handling properties.
