Description

4,4'-Diamino-3,3',5,5'-Tetrabromobiphenyl is a high-purity, halogenated aromatic amine compound that serves as a critical advanced intermediate in the synthesis of high-performance polymers and specialty chemicals. Its value lies in the unique combination of bromine's flame-retardant properties and the reactivity of the amine groups, enabling the creation of materials with enhanced thermal stability and specific functional characteristics. This product is essential for R&D and production in industries focused on developing next-generation flame retardants, high-temperature resins, and specialized dyes or pigments.

Application

• Flame Retardant Synthon: A key building block for synthesizing novel brominated flame retardants used in engineering plastics, textiles, and electronic encapsulants.
• High-Performance Polymer Intermediate: Used in the production of polyimides, polyamides, and other heat-resistant polymers for aerospace, automotive, and electronics applications.
• Specialty Dye and Pigment Manufacturing: Serves as a precursor for creating complex, color-fast organic pigments and dyes.
• Pharmaceutical Intermediate: Employed in the research and synthesis of active pharmaceutical ingredients (APIs) requiring halogenated biphenyl structures.
• Liquid Crystal and OLED Materials: Acts as a core component in the development of advanced organic electronic materials.
• Cross-linking Agent: Utilized in epoxy and other thermoset resin systems to modify mechanical and thermal properties.

Quality Control

Every batch of 4,4'-Diamino-3,3',5,5'-Tetrabromobiphenyl is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and customer-specific requirements. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to guarantee consistent quality and traceability for your critical applications.

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 light-sensitive nature and propensity for oxidation, it is recommended to store the material under an inert atmosphere for long-term preservation. Keep away from strong oxidizing agents.
