Description

2,3,3',4,4',5,6-Heptabromodiphenyl Ether is a high-purity brominated aromatic compound, specifically a heptabrominated congener of diphenyl ether. This specialty chemical is valued for its role as a key intermediate and reference standard in advanced material science and environmental analysis. It is primarily required by research institutions and industrial laboratories focused on flame retardant development, environmental fate studies, and analytical method validation.

Application

• Flame Retardant Research & Development: Serves as a critical intermediate or model compound in the synthesis and study of novel brominated flame retardants (BFRs) for polymers and textiles.
• Environmental & Analytical Chemistry: Used as a certified reference material (CRM) or analytical standard for the quantification and identification of polybrominated diphenyl ethers (PBDEs) in environmental, food, and biological samples via GC-MS or HPLC.
• Toxicological Studies: Employed in scientific research to investigate the environmental persistence, bioaccumulation, and toxicological profiles of higher brominated diphenyl ether congeners.
• Material Science: Acts as a precursor or additive in the development of specialized polymeric materials with specific fire-resistant properties.
• Regulatory Compliance Testing: Essential for laboratories performing compliance testing for restricted substances (e.g., RoHS, REACH) to calibrate equipment and validate analytical methods.
