The demand for enhanced fire safety in materials is a constant driving force across numerous industries, from electronics and construction to automotive and textiles. Flame retardants are essential for meeting these requirements, and at the core of many high-performance flame retardant formulations are specialized chemical intermediates. 3,3′,5,5′-Tetrabromobiphenyl (TBB), identified by CAS 79-94-7, is a prominent example, serving as a critical building block in the creation of advanced fire-retardant solutions.

Understanding TBB: Properties and Purity

3,3′,5,5′-Tetrabromobiphenyl is a brominated aromatic compound, typically supplied as an off-white to yellow powder. Its molecular formula is C12H6Br4, with a molecular weight of approximately 469.79 g/mol. Key physical properties include a density of 2.14 g/cm³ and a high boiling point of 401.8°C, indicating its robustness under thermal stress. For its intended applications, the purity of TBB is paramount, with manufacturers generally ensuring a minimum purity of ≥98%, often reaching 99.5%. This high purity is crucial for ensuring predictable reactivity and efficacy when incorporated into complex formulations, preventing unwanted side reactions or impurities in the final product.

TBB's Role in Flame Retardant Systems

The significant bromine content in TBB makes it an exceptionally effective intermediate for synthesizing various brominated flame retardants (BFRs). When incorporated into polymers or other materials, these BFRs interfere with the combustion process by releasing bromine radicals, which quench the flame propagation cycle. TBB's structure allows it to be chemically bound into polymer matrices, leading to durable flame-retardant properties that do not easily leach out. This makes it suitable for applications where long-term performance and resistance to environmental exposure are required. Industries rely on such intermediates to meet stringent fire safety standards in products like printed circuit boards, electrical insulation, and engineered plastics.

Procuring TBB for Industrial Needs

For B2B buyers seeking to procure 3,3′,5,5′-Tetrabromobiphenyl, it is essential to partner with reliable manufacturers and suppliers. Key considerations for purchasing include:

  • Supplier Credibility: Select suppliers with a proven history of providing high-quality chemical intermediates and excellent customer service.
  • Quality Assurance: Always request and verify the Certificate of Analysis (CoA) to confirm the purity and specifications of the TBB.
  • Competitive Pricing: Research market prices and obtain quotes from multiple sources to ensure you are getting a fair price for your bulk purchases.
  • Supply Chain Stability: Ensure the supplier has a robust supply chain and can guarantee consistent delivery to meet your production schedules.
