Description

4-Bromophenylacetyl Chloride is a versatile and reactive organic intermediate essential for advanced chemical synthesis. Its primary value lies in its acyl chloride functional group, which readily undergoes nucleophilic substitution to form amides, esters, and other derivatives, enabling the efficient construction of complex molecular architectures. This compound is particularly critical for researchers and manufacturers in the pharmaceutical and agrochemical industries, where it serves as a key building block for active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring a brominated phenylacetyl moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that incorporate halogenated aromatic structures.
• Liquid Crystal & OLED Material Production: Serves as a building block for advanced organic electronic materials and liquid crystal displays (LCDs).
• Peptide & Protein Research: Employed as an acylating agent for modifying amino acids or protecting groups in peptide synthesis.
• Dye & Pigment Manufacturing: Acts as an intermediate in the synthesis of complex organic dyes and colorants.
• Polymer Chemistry: Utilized to introduce functional side chains or as a monomer modifier in specialty polymer production.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D in medicinal chemistry and material science.

Quality Control

Our 4-Bromophenylacetyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high purity and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory compliance needs.

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) after opening to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
