Description

2,2',3,3',4,5',6-Heptachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant importance for analytical and research purposes, serving as a critical reference standard for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, PCB fate and transport studies, and method development.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification and identification of PCB congeners in soil, water, sediment, and biota samples via GC-MS or GC-ECD.
• Toxicological Research: Employed in laboratory studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual PCB congeners.
• Method Development & Validation: Serves as a critical component in developing, calibrating, and validating analytical methods for PCB detection and congener-specific analysis.
• Quality Control & Assurance: Used as an internal standard or spike recovery standard to ensure accuracy and precision in commercial and regulatory environmental testing laboratories.
• Regulatory Compliance Testing: Essential for laboratories performing analysis to comply with global regulations concerning PCBs, such as the Stockholm Convention on POPs, EPA methods, and other international standards.
• Forensic Environmental Chemistry: Aids in source identification and apportionment in environmental forensic investigations related to PCB contamination.
