Description

Cloransulam-Methyl CAS NO 147150-35-4 is a selective, systemic herbicide belonging to the sulfonamide chemical class. This compound is valued for its high efficacy in controlling a broad spectrum of broadleaf weeds, particularly in major row crops. It is a critical active ingredient for agricultural formulators and manufacturers seeking reliable, post-emergence weed management solutions. The product is essential for the production of advanced herbicide formulations used in global agriculture.

Application

• Primary Use in Soybean Crops: Selective post-emergence control of troublesome broadleaf weeds such as velvetleaf, pigweed, and lambsquarters.
• Corn and Maize Protection: Formulated for use in corn to manage key weed species without harming the crop.
• Agricultural Formulations: Serves as a key technical-grade active ingredient (TC) for the manufacturing of emulsifiable concentrates (EC), suspension concentrates (SC), and water-dispersible granules (WG).
• Integrated Weed Management Programs: Used in rotation or tank-mix combinations with other herbicides to prevent herbicide resistance.
• Non-Crop Area Management: Applicable in certain non-agricultural settings for industrial vegetation control.

Quality Control

Our Cloransulam-Methyl is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. Every lot is analyzed against comprehensive specifications using advanced techniques like HPLC. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee compliance with your formulation requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after initial use to prevent moisture absorption and degradation. Keep away from heat, sparks, and open flame.
