Description

2,2',3,4,4',5,6-Heptabromodiphenyl Ether is a specific, high-bromine congener within the polybrominated diphenyl ether (PBDE) family of flame retardants. This compound is valued for its precise chemical structure and high bromine content, which are critical for research into the environmental fate, toxicology, and analytical detection of brominated flame retardants. It serves as a vital certified reference material (CRM) and analytical standard for laboratories in environmental monitoring, regulatory compliance testing, and advanced material science research.

Application

• Certified Reference Material (CRM): Primary use as a high-purity standard for the calibration of analytical equipment (GC-MS, LC-MS) and for quality control in testing laboratories.
• Environmental Analysis: Critical for the accurate quantification and monitoring of PBDE congeners in soil, water, sediment, and biota samples to assess pollution levels and ecological impact.
• Toxicological Research: Used in studies to investigate the specific biological effects, metabolic pathways, and health implications of individual PBDE compounds.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for brominated flame retardants in complex matrices.
• Regulatory Compliance Testing: Supports testing for compliance with global regulations (e.g., REACH, RoHS, TSCA) that restrict or require reporting of specific PBDE congeners.
• Product Safety & Material Science: Used in research to study the leaching, degradation, and formation of PBDEs from treated materials and in the development of alternative flame retardants.
