Description

Tetrabromoterephthalic Acid Dichloride is a highly functionalized aromatic acid chloride derivative, serving as a critical reactive intermediate in advanced organic synthesis. Its value lies in introducing both high bromine content and reactive acyl chloride functionality into target molecules, enabling the creation of specialized polymers and flame retardants. This compound is essential for R&D chemists and production engineers in the polymer additives, specialty chemicals, and advanced material sectors seeking to enhance thermal stability and flame resistance in their products.

Application

• Flame Retardant Synthon: A key building block for synthesizing novel brominated flame retardants used in engineering plastics, textiles, and epoxy resins.
• Polymer Modification: Used as a reactive comonomer or chain terminator to incorporate bromine into polymer backbones, such as polyesters, polyamides, and polycarbonates, to impart inherent flame retardancy.
• Specialty Chemical Intermediate: Serves in the production of high-performance dyes, pigments, and liquid crystal compounds where bromine atoms are required for specific electronic or steric properties.
• Cross-linking Agent: Employed in the formulation of heat-resistant and fire-retardant coatings, adhesives, and sealants.
• Pharmaceutical & Agrochemical Research: Utilized as a versatile intermediate in the research and development of bioactive molecules.
• Laboratory Reagent: Acts as a specialized reagent for bromination and acylation reactions in academic and industrial research settings.

Quality Control

Our Tetrabromoterephthalic Acid Dichloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Production adheres to ISO 9001 quality management principles. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles, available upon request. We support our clients' compliance needs for REACH and other global regulatory frameworks.

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 (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong bases, alcohols, and moisture.
