Description

2,2',3,4,5',6-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for research, analytical, and regulatory compliance purposes due to its persistence and environmental impact. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in toxicology studies, method development, and the calibration of analytical instrumentation for the detection of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Serves as a certified reference material (CRM) for the qualitative and quantitative analysis of PCBs in environmental, food, and biological samples via GC-MS or HPLC.
• Environmental Monitoring: Used in the calibration and validation of testing protocols to monitor PCB contamination in soil, water, sediment, and air to comply with global environmental regulations (e.g., Stockholm Convention).
• Toxicological Research: Employed in scientific studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual PCB congeners.
• Method Development & Validation: Critical for developing, optimizing, and accrediting new analytical methods for PCB detection and quantification in complex matrices.
• Quality Control/Assurance: Acts as a spike or internal standard in laboratory QC procedures to ensure accuracy, precision, and reliability of analytical data.
• Regulatory Compliance Testing: Essential for laboratories performing mandated testing for industries such as waste management, manufacturing, and import/export to verify non-compliance with PCB restrictions.
