Description

2,2',3,5,5',6-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is essential for analytical and research applications where precise chemical standards are required for calibration, method development, and environmental monitoring. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, toxicology studies, and regulatory compliance.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and HPLC systems in environmental analysis.
• Environmental Monitoring: Quantification and congener-specific profiling of PCBs in soil, water, sediment, and biota samples to assess contamination levels.
• Toxicological Research: Used in laboratory studies to investigate the specific metabolic pathways, bioaccumulation, and toxic effects of individual PCB congeners.
• Method Development & Validation: Serves as a critical component in developing and validating new analytical methods for POP detection and quantification.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike recovery standard to ensure accuracy and precision in analytical testing protocols.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with international regulations such as the Stockholm Convention, EPA methods, and other global environmental directives.
