Description

5-Bromoisophthaloyl Dichloride is a high-purity, reactive aromatic diacid chloride derivative, serving as a critical building block in advanced organic synthesis. Its value lies in providing a bromine-functionalized aromatic core, enabling the introduction of both carboxylic acid and halogen functionalities in a single step for precise molecular construction. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries who require a reliable, high-quality intermediate for creating complex target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly for compounds requiring brominated aromatic scaffolds.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides where the bromine substituent modulates biological activity.
• Ligand and Catalyst Development: Serves as a starting material for creating sophisticated chelating ligands and organometallic catalysts used in cross-coupling reactions.
• Polymer Chemistry: A monomer for the production of high-performance polyamides, polyimides, and other specialty polymers with enhanced thermal and mechanical properties.
• Material Science: Building block for metal-organic frameworks (MOFs) and covalent organic frameworks (COFs) with tailored porosity and functionality.
• Chemical Research: Versatile reagent in academic and industrial R&D for exploring new synthetic methodologies and creating novel chemical entities.

Quality Control

Our 5-Bromoisophthaloyl Dichloride is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including assay by titration, identification by FT-IR, and impurity profiling. Certificates of Analysis (COA) detailing all specifications and test results are 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, 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 hydrolysis. Keep away from strong bases, alcohols, and water.
