Description

Mesosulfuron [Iso] CAS NO 400852-66-6 is a high-purity sulfonylurea herbicide intermediate, specifically the isomer of mesosulfuron-methyl. This compound is critical for the synthesis of advanced, low-dose herbicides that offer superior weed control with enhanced crop safety. It is primarily required by agrochemical manufacturers and R&D facilities focused on developing next-generation selective herbicides for cereal crops like wheat and barley.

Application

• Primary Intermediate for the synthesis of mesosulfuron-methyl herbicide.
• Agrochemical R&D for developing new sulfonylurea-based weed control solutions.
• Formulation Studies to create stable and effective commercial herbicide products.
• Production of selective post-emergence herbicides targeting broadleaf weeds and grasses in cereals.
• Reference Standard for quality control and analytical method development in agrochemical labs.

Quality Control

Our Mesosulfuron [Iso] is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for agrochemical synthesis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment.

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 to prevent degradation from atmospheric moisture.
