Description

Methyl Chloroacetate CAS NO 96-34-4 is a versatile organic ester and a key alkylating agent in fine chemical synthesis. Its high reactivity, stemming from the active chlorine atom on the α-carbon, makes it an indispensable building block for the production of agrochemicals, pharmaceuticals, and specialty chemicals. This compound is essential for manufacturers and R&D laboratories seeking a reliable and efficient reagent for introducing the carboxymethyl group or for further functionalization in multi-step synthesis.

Application

• Agrochemical Intermediates: A critical precursor in the synthesis of herbicides, insecticides, and plant growth regulators.
• Pharmaceutical Synthesis: Used as an alkylating agent in the manufacture of active pharmaceutical ingredients (APIs) and various drug intermediates.
• Dye and Pigment Production: Serves as a key intermediate in the synthesis of certain dyes and organic pigments.
• Polymer Modification: Employed in the production of specialty polymers and as a monomer for certain acrylic esters.
• Organic Synthesis Reagent: Utilized in laboratories and industrial settings for esterification, condensation, and nucleophilic substitution reactions.
• Surfactant and Flavor/Fragrance Intermediates: Acts as a building block for the synthesis of certain surfactants and aroma chemicals.

Quality Control

Our Methyl Chloroacetate is produced under stringent quality management systems. Every batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications for industrial and laboratory use. Certificates of Analysis (COA) with detailed batch-specific results are provided to guarantee traceability and consistency.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases, strong oxidizing agents, and strong reducing agents. Due to its highly volatile and hygroscopic nature, containers must be kept tightly sealed and under dry conditions to prevent moisture absorption and evaporation.
