Description

(±)-2-(4-Chloro-2-Methylphenoxy)Propionic Acid Sodium Salt CAS NO 40951-62-0 is the sodium salt derivative of the widely used phenoxy herbicide mecoprop. This formulation offers enhanced water solubility and handling stability, making it a critical technical-grade intermediate for agrochemical manufacturing. It is primarily required by producers of selective herbicide formulations targeting broadleaf weeds in cereal crops, turf, and non-crop areas. Our supply ensures consistent quality and reliable availability for industrial-scale synthesis.

Application

• Primary Agrochemical Intermediate: Key raw material for the synthesis of mecoprop-P and other phenoxyalkanoic acid herbicide formulations.
• Selective Herbicide Production: Used in manufacturing post-emergence herbicides for controlling broadleaf weeds in wheat, barley, oats, and rye.
• Turf Management: Found in formulations for weed control in lawns, golf courses, and sports fields.
• Industrial Vegetation Control: Component in herbicides for managing weeds along railways, roadsides, and utility rights-of-way.
• Research & Development: Serves as a standard or starting material in agricultural chemical R&D for new formulation studies.
• Manufacturing of Salt-Based Formulations: Utilized to produce soluble concentrates (SL) and other salt-based agrochemical products for improved application.

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). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation. Keep away from heat, sparks, and open flame.
