Description

1,4-Benzenedicarbonyl Dichloride,2-Bromo- CAS NO 13815-89-9 is a high-purity, brominated derivative of terephthaloyl chloride, serving as a critical bifunctional monomer and reactive intermediate. Its value lies in introducing both electrophilic reactivity and a bromine functional handle into polymer backbones and complex organic molecules, enabling precise structural modifications. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require specialized building blocks for synthesizing high-performance polymers, liquid crystals, and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in creating brominated aromatic cores for kinase inhibitors and other targeted therapies.
• High-Performance Polymer Synthesis: Monomer for producing brominated polyamides, polyesters, and polyimides, which exhibit enhanced flame retardancy, thermal stability, and mechanical properties.
• Liquid Crystal Materials: Used in the preparation of brominated aromatic units for liquid crystal displays (LCDs) and other optoelectronic materials.
• Agrochemical Synthesis: Intermediate in the production of advanced herbicides and fungicides that require a brominated aromatic structure for optimal bioactivity.
• Cross-Linking Agent: Functions as a reactive site in the creation of cross-linked polymer networks for coatings, adhesives, and composite materials.
• Organic Synthesis Reagent: Employed in laboratory-scale organic reactions, such as Friedel-Crafts acylation, to introduce the 2-bromoterephthaloyl moiety into complex molecules.
• Material Science Research: Serves as a precursor for Metal-Organic Frameworks (MOFs) and other porous materials where the bromine atom can be further functionalized.

Quality Control

Our 1,4-Benzenedicarbonyl Dichloride,2-Bromo- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; it must be kept under an inert atmosphere (e.g., nitrogen or argon) in its original sealed packaging to prevent hydrolysis and degradation. Keep away from heat, open flames, and incompatible materials.
