Description

2,3,3',4',5',6-Hexachlorobiphenyl CAS NO 74472-45-0 is a specific, high-purity congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant importance as a critical reference standard and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily needed by analytical laboratories, research institutions, and environmental agencies engaged in the precise identification and quantification of PCB contaminants in various matrices.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for calibrating instruments and validating methods in the analysis of soil, water, sediment, and biota samples.
• Food Safety Testing: Serves as a critical standard in the quantification of PCB residues in food and feed products to ensure compliance with international safety regulations.
• Toxicological and Biomedical Research: Employed in studies investigating the metabolism, distribution, and chronic health effects of specific PCB congeners.
• Regulatory Compliance and Method Development: Essential for laboratories developing and accrediting analytical methods according to standards from the EPA, EU, and other global regulatory bodies.
• Waste and Remediation Site Characterization: Used to accurately profile PCB congener patterns at industrial sites and in waste materials for effective remediation planning.
• Quality Control in Manufacturing: Acts as a purity standard for companies producing or handling specialized chemicals where PCB contamination must be rigorously excluded.
