Description

2,2',3,3',6,6'-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance for research, analytical, and regulatory 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 quality control programs.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of instruments like GC-MS and HPLC in environmental analysis.
• Environmental Monitoring: Serves as a critical standard for quantifying PCB contamination in soil, water, sediment, and biological samples to meet regulatory compliance (e.g., EPA methods).
• 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 and quantification of PCBs.
• Quality Assurance/Quality Control (QA/QC): Used as a spike or internal standard in laboratory QA/QC protocols to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Provides a benchmark for testing products and materials to ensure they meet international restrictions on PCBs (e.g., Stockholm Convention, REACH).
