Description

2,2',3,3',5,6,6'-Heptachlorobiphenyl CAS NO 52663-64-6 is a specific congener of polychlorinated biphenyls (PCBs), characterized by its seven chlorine substituents on the biphenyl ring system. This compound is of significant importance for analytical and research purposes, particularly in environmental monitoring and toxicological studies. It is primarily needed by analytical laboratories, regulatory agencies, and research institutions involved in the identification, quantification, and fate analysis of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Serves as a critical certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Monitoring: Used as a marker compound for the detection and quantification of PCB contamination in soil, water, sediment, and air samples.
• Toxicology Research: Employed in scientific studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of heptachlorinated biphenyl congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for PCB congener-specific analysis.
• Quality Assurance/Quality Control (QA/QC): Used as a spike or control standard to ensure the accuracy and precision of analytical data in compliance with regulatory methods.
• Forensic Analysis: Aids in source identification and fingerprinting of PCB mixtures in environmental forensic investigations.
