Description

Diethylammonium (S)-2-(4-Chloro-2-Methylphenoxy)Propionate is a high-purity, chiral ammonium salt derivative of a phenoxypropionic acid herbicide precursor. This compound is of significant commercial importance as a key intermediate in the synthesis of advanced enantiomerically pure agrochemicals, particularly selective post-emergence herbicides. It is primarily required by fine chemical manufacturers and agrochemical R&D facilities for the production of high-efficacy crop protection agents.

Application

• Agrochemical Intermediate: A critical chiral building block for the synthesis of enantiomerically pure phenoxypropionate herbicides.
• Herbicide Production: Used in manufacturing selective herbicides targeting broadleaf weeds in cereal crops like wheat and barley.
• Fine Chemical Synthesis: Serves as a specialized intermediate in organic synthesis for creating compounds with specific stereochemistry.
• Research & Development: Employed in agricultural chemical R&D for developing new, more selective, and environmentally benign herbicide formulations.
• Active Ingredient (AI) Precursor: Processed to yield the active acidic form of herbicides such as (S)-2-(4-chloro-2-methylphenoxy)propanoic acid (Mecoprop-P).

Quality Control

Our Diethylammonium (S)-2-(4-Chloro-2-Methylphenoxy)Propionate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity assay and impurity profile analysis, to ensure it meets exacting specifications for use in fine chemical synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity (typically >98.5%), enantiomeric excess (>99%), and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. This material is hygroscopic (moisture-sensitive); ensure containers are sealed after use to prevent absorption of atmospheric moisture.
