Description

2,2',3,3',4,4',5,6,6'-Nonabde CAS NO 437701-79-6 is a specific, high-purity congener of polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants. This compound is of significant importance for research, analytical, and regulatory compliance purposes within the chemical and environmental sectors. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions for use as a certified reference material, analytical standard, and for toxicological and environmental fate studies.

Application

• Certified Reference Material (CRM) for the calibration of analytical instruments and validation of test methods.
• Analytical Standard for the accurate quantification of PBDE congeners in environmental, food, and biological samples via GC-MS or LC-MS.
• Environmental Monitoring and research into the distribution, persistence, and bioaccumulation of brominated flame retardants.
• Toxicological Studies to investigate the health and ecological impacts of specific PBDE congeners.
• Regulatory Compliance Testing to ensure products and materials meet global restrictions on persistent organic pollutants (POPs).
• Method Development in analytical chemistry laboratories for the detection of halogenated organic compounds.
• Quality Control in laboratories performing high-precision analysis of complex matrices.
