Description

2-Methyl-4-Chlorophenoxyacetic Acid (CAS NO 94-74-6) is a synthetic auxin-type herbicide intermediate of significant commercial importance. This compound serves as a key precursor in the synthesis of MCPA, a widely used selective herbicide for controlling broadleaf weeds in cereal crops and turf. It is essential for agrochemical manufacturers, research institutions, and formulators developing effective and targeted crop protection solutions. The consistent quality and purity of this intermediate are critical for ensuring the efficacy and safety of the final herbicide products.

Application

• Primary Intermediate for MCPA Herbicide: The principal and most significant application is as the direct precursor in the commercial synthesis of the herbicide MCPA (2-methyl-4-chlorophenoxyacetic acid).
• Agrochemical Research & Development: Used in R&D laboratories for developing new herbicide formulations, studying structure-activity relationships, and creating derivative compounds.
• Selective Weed Control Systems: Integral to manufacturing products designed for post-emergence control of annual and perennial broadleaf weeds in wheat, barley, oats, rice, and grasslands.
• Turf and Lawn Management: Found in formulations for professional turf management to control weeds like chickweed and clover without harming grasses.
• Industrial Vegetation Control: Used in systems for managing unwanted vegetation in non-crop areas such as roadsides, railways, and industrial sites.
• Chemical Synthesis Reference Standard: Serves as a high-purity analytical standard for quality control testing in agrochemical production and regulatory compliance.
