Description

2,3,3',4,4',5,5'-Heptabromobiphenyl is a high-purity, polybrominated biphenyl (PBB) compound, identified by CAS NO 88700-06-5. This specialty brominated aromatic is valued for its role as a key intermediate and reference standard in advanced chemical research and development. It is primarily required by industrial R&D laboratories and chemical manufacturers focused on flame retardant studies, environmental analysis, and the synthesis of complex halogenated organic molecules.

Application

• Flame Retardant Research & Development: Serves as a critical intermediate and model compound for developing and testing new brominated flame retardant systems.
• Environmental & Analytical Chemistry: Used as a certified reference material (CRM) and analytical standard for the detection and quantification of polybrominated biphenyls (PBBs) in environmental, food, and biological samples.
• Toxicological & Safety Studies: Employed in scientific research to investigate the environmental fate, bioaccumulation, and toxicological profile of persistent organic pollutants (POPs).
• Organic Synthesis: Acts as a specialized building block for synthesizing more complex halogenated aromatic compounds for advanced material science applications.
• Regulatory Compliance Testing: Essential for laboratories performing compliance testing against international regulations (e.g., RoHS, REACH, TSCA) concerning restricted brominated compounds.
