Description

2,2',3,4,5,6-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). 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, method development, and quality control.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of gas chromatography (GC) and mass spectrometry (MS) systems in environmental analysis.
• Environmental Monitoring: Quantification and confirmation of PCB congeners in soil, water, sediment, and air samples to assess contamination levels and track pollutant sources.
• Toxicological Research: Used in scientific studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods for PCB detection and quantification according to EPA, ISO, or other international standards.
• Quality Assurance/Quality Control (QA/QC): Serves as a spike or internal standard in laboratory procedures to ensure accuracy, precision, and reliability of analytical data.
• Regulatory Compliance Testing: Used by commercial and government labs to test products, waste streams, and environmental samples for compliance with global regulations like the Stockholm Convention on POPs.
