Description

Methyl (2R)-2-[4-(2,4-Dichlorophenoxy)Phenoxy]Propanoate CAS NO 71283-65-3 is a chiral phenoxypropanoate ester, a key intermediate in the synthesis of enantiomerically pure agrochemicals. This compound matters for its role in producing high-efficacy, optically active herbicides, offering superior selectivity and environmental profile compared to racemic mixtures. It is essential for manufacturers in the agrochemical and fine chemical industries developing next-generation crop protection agents and other specialty products.

Application

• Key Intermediate for Chiral Herbicides: Primary use in the synthesis of enantiomerically pure phenoxypropanoic acid herbicides, such as (R)-dichlorprop.
• Agrochemical Research & Development: Serves as a critical building block in R&D for novel, high-selectivity plant growth regulators and weed control agents.
• Fine Chemical Synthesis: Used in asymmetric synthesis for creating complex molecules with defined stereochemistry in pharmaceutical and specialty chemical applications.
• Process Chemistry: Employed in scale-up and manufacturing processes where optical purity is critical for product performance and regulatory approval.
