Description

2,3',4,4',5',6-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest in environmental analysis, toxicology research, and regulatory compliance testing due to its persistence and potential bioaccumulation. It serves as a critical reference standard and analytical standard for laboratories and research institutions worldwide.

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of instruments (GC-MS, HPLC) in environmental and food safety testing.
• Environmental Monitoring: Quantification and congener-specific analysis of PCBs in soil, sediment, water, and air samples for pollution assessment.
• Toxicological Research: Used in studies to investigate the biochemical pathways, metabolic fate, and chronic health effects of specific PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical methods for PCB detection and quantification.
• Quality Control/Assurance: Serves as an internal or external standard in laboratory QC protocols to ensure accuracy and precision in PCB analysis.
• Regulatory Compliance Testing: Supports testing mandated by agencies (e.g., EPA, EU directives) for PCB levels in consumer products, industrial effluents, and waste materials.
