Description

2,2',4,4',5,6'-Hexabromodiphenyl Ether is a specific, high-bromine congener of the polybrominated diphenyl ether (PBDE) family. This compound is valued for its role as a reference standard and a critical material in environmental and analytical research. It is primarily needed by analytical laboratories, research institutions, and regulatory bodies focused on persistent organic pollutant (POP) analysis, environmental monitoring, and toxicological studies. Its defined structure is essential for the accurate calibration of instruments and the quantification of brominated flame retardant residues in various matrices.

Application

• Analytical Reference Standard: Primary use for calibrating GC-MS, LC-MS, and other analytical equipment for the detection and quantification of PBDEs.
• Environmental Research: Used in studies to understand the environmental fate, transport, and degradation pathways of brominated flame retardants.
• Toxicological Studies: Serves as a precise test material for investigating the biological effects, bioaccumulation, and metabolic pathways of specific PBDE congeners.
• Method Development & Validation: Critical for developing and validating new analytical methods for POPs in compliance with international standards like EPA methods.
• Quality Control & Assurance: Employed as an internal standard or spike in laboratory QC/QA protocols to ensure accuracy and precision in analytical data.
• Regulatory Compliance Testing: Used by testing laboratories to screen and confirm the presence of restricted brominated compounds in consumer products, waste streams, and environmental samples.
