Description

2,3',4,4'5,5'-Hexabromobiphenyl is a highly brominated derivative of biphenyl, a member of the polybrominated biphenyl (PBB) family. This compound is valued for its role as a flame retardant intermediate and a critical reference standard in environmental and analytical chemistry. It is primarily required by research institutions, chemical manufacturers, and analytical laboratories involved in material science, regulatory compliance testing, and environmental monitoring of persistent organic pollutants (POPs).

Application

• As a reference standard for the calibration of analytical equipment (GC-MS, HPLC) in the detection and quantification of brominated flame retardants.
• Used in scientific research to study the environmental fate, bioaccumulation, and toxicology of polybrominated biphenyls.
• Serves as a key intermediate in the synthesis of specialized flame-retardant formulations for polymers and plastics.
• Essential for regulatory compliance testing and quality control in industries monitoring for POPs under international treaties like the Stockholm Convention.
• Employed in the development and validation of analytical methods for food, feed, and environmental sample analysis.
