Description

Chlorimuron CAS NO 99283-00-8 is a selective, post-emergence sulfonylurea herbicide known for its high efficacy at low application rates. This compound is critical for modern agricultural practices, offering reliable control of a broad spectrum of broadleaf weeds and certain grasses in key legume crops. It is an essential tool for agronomists and formulators seeking to develop effective and sustainable crop protection solutions for global soybean, peanut, and other legume production systems.

Application

• Primary Use in Soybean Crops: Widely applied for post-emergence control of troublesome weeds like cocklebur, morning glory, and velvetleaf.
• Peanut Crop Protection: Used to manage broadleaf weed populations without harming the developing peanut plants.
• Formulation Ingredient: Serves as a key active ingredient in the manufacture of various herbicide formulations, including wettable powders (WP) and suspension concentrates (SC).
• Agricultural Research & Development: Employed as a reference standard and intermediate in the synthesis and testing of new agrochemical compounds.
• Non-Crop Area Weed Management: Utilized in certain industrial and right-of-way vegetation control programs.

Quality Control

Our Chlorimuron is produced under a stringent quality management system to ensure batch-to-batch consistency and high purity. Every lot is analyzed against rigorous internal specifications, which typically include assay by HPLC, identification by IR spectroscopy, and limits for key impurities and moisture content. A Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. The product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture.
