Description

4-Chlorobenzeneacetyl Chloride is a versatile and reactive aromatic acid chloride derivative, serving as a critical building block in advanced organic synthesis. Its primary value lies in its ability to introduce the 4-chlorophenylacetyl moiety, a key structural feature in various high-value compounds. This intermediate is essential for research and production in the pharmaceutical and agrochemical industries, where it is used to create active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting neurological and inflammatory pathways.
• Agrochemical Synthesis: Used in the manufacture of herbicides, fungicides, and plant growth regulators containing chlorinated aromatic structures.
• Dye and Pigment Manufacturing: Acts as an intermediate for producing specialized azo dyes and organic pigments.
• Polymer Chemistry: Employed as a monomer or modifying agent for engineering plastics and high-performance polymers.
• Liquid Crystal & OLED Materials: Serves as a building block for electronic chemicals used in display technologies.
• Custom Synthesis & Contract Manufacturing: A valuable reagent for research laboratories and CDMOs developing novel chemical entities.

Quality Control

Our 4-Chlorobenzeneacetyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and IR for identity confirmation, to ensure it meets exacting standards for research and industrial use. A comprehensive Certificate of Analysis (COA) detailing purity, impurities, and physical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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) after opening. Keep away from strong bases, oxidizing agents, and sources of ignition.
