Description

2,2',3,5,6,6'-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance for research, analytical, and regulatory compliance applications where precise chemical standards are required. It is primarily needed by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in method development, calibration, and the synthesis of reference materials.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and other analytical instruments in environmental and food safety testing.
• Environmental Monitoring: Serves as a critical standard for quantifying PCB contamination in soil, water, sediment, and air samples to meet regulatory requirements.
• Toxicological Research: Employed in scientific studies to investigate the specific biological effects, metabolic pathways, and environmental fate of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for the detection of PCBs in complex matrices.
• Quality Control/Assurance: Used as a spike or control standard in laboratory QC/QA protocols to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Provides a benchmark for compliance testing against international regulations such as the Stockholm Convention on Persistent Organic Pollutants (POPs).
