Description

1,3-Benzenedicarbonyl Dichloride,4-Bromo- CAS NO 63192-68-7 is a high-purity brominated aromatic diacid chloride derivative, serving as a critical building block in advanced organic synthesis. This compound is valued for its dual reactive sites, enabling the controlled introduction of both the isophthaloyl and bromophenyl moieties into complex molecular architectures. It is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and specialty polymer industries for the development of novel active ingredients and high-performance materials.

Application

• Pharmaceutical Intermediate: Key synthon for the production of brominated active pharmaceutical ingredients (APIs), protease inhibitors, and kinase inhibitors.
• Agrochemical Synthesis: Used in the manufacture of advanced herbicides, fungicides, and plant growth regulators requiring bromo-aromatic functionality.
• Polymer & Material Science: Monomer for synthesizing brominated polyamides, polyimides, and epoxy resins, imparting flame retardancy and enhanced thermal stability.
• Liquid Crystal & OLED Materials: Building block for brominated aromatic cores in electronic and photonic materials.
• Cross-linking Agent: Functions as a reactive linker in peptide synthesis and dendrimer construction.
• Organic Synthesis Reagent: Employed in Friedel-Crafts acylation and other reactions to introduce the 4-bromoisophthaloyl group.

Quality Control

Every batch of 1,3-Benzenedicarbonyl Dichloride,4-Bromo- undergoes rigorous analytical testing to ensure it meets the stringent purity requirements for synthetic applications. Our quality system is designed to guarantee batch-to-batch consistency and reliability. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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 to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
