Description

4-(2-Bromophenyl)Butanoyl Chloride is a versatile and reactive organic intermediate, specifically an acid chloride derivative of a brominated phenylbutyric acid. Its value lies in its dual functionality, where the acid chloride group offers high reactivity for amide and ester formation, and the bromophenyl moiety provides a handle for further cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical sectors, serving as a key building block for synthesizing more complex molecules, including potential active pharmaceutical ingredients (APIs) and advanced materials.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders or acting as enzyme inhibitors.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the bromine atom allows for further structural diversification.
• Liquid Crystal & OLED Material Production: Serves as a building block for creating specialized organic molecules used in electronic displays and lighting.
• Polymer Chemistry: Can be incorporated into polymer chains as a monomer or used to modify polymer backbones to introduce specific brominated aromatic properties.
• Organic Synthesis & Research: A valuable reagent in academic and industrial R&D labs for constructing complex organic architectures via reactions like Friedel-Crafts acylation, amidation, and Suzuki coupling.
• Chemical Intermediate for Dyes & Pigments: Acts as a starting material for synthesizing brominated aromatic compounds used in colorants.

Quality Control

Every batch of 4-(2-Bromophenyl)Butanoyl Chloride is manufactured under strict quality management protocols. We employ advanced analytical techniques, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each 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 place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature and reactivity as a strong acid/organic solvent, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as bases, alcohols, and oxidizing agents.
