Description

4-Chlorophenoxyacetyl Chloride is a versatile and highly reactive organic acid chloride derivative, serving as a critical building block in advanced chemical synthesis. Its primary value lies in its ability to efficiently introduce the 4-chlorophenoxyacetyl moiety, a key functional group for modifying biological activity and material properties. This intermediate is essential for research and production in the pharmaceutical and agrochemical industries, where it is used to develop active ingredients and novel compounds.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for antibiotics and other therapeutic agents.
• Agrochemical Synthesis: Used in the production of herbicides, pesticides, and plant growth regulators, leveraging the phenoxyacetic acid backbone.
• Peptide Chemistry: Acts as an acylating agent for the modification of amino acids and peptides during custom synthesis.
• Dye and Pigment Manufacturing: Serves as an intermediate in creating specialized chromophores and functional dyes.
• Polymer Modification: Employed to introduce specific chlorophenoxy groups into polymer chains to alter physical or chemical characteristics.
• Research & Development: A valuable reagent in organic chemistry labs for constructing complex molecules and exploring new synthetic pathways.

Quality Control

Our 4-Chlorophenoxyacetyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements of industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic and moisture-sensitive nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from strong bases, oxidizing agents, and sources of ignition.
