Description

2,2',3,4,4',5,5',6-Octachlorobiphenyl is a specific, highly chlorinated congener of the polychlorinated biphenyl (PCB) family, identified by CAS NO 52663-76-0. This compound is of significant importance for analytical and research purposes, serving as a critical reference standard for environmental monitoring and toxicological studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method development.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification and identification of PCB congeners in soil, water, sediment, and air samples.
• Food and Feed Safety Testing: Serves as an analytical standard in laboratories monitoring PCB contamination levels in food products, animal feed, and edible oils to ensure regulatory compliance.
• Toxicological and Biomedical Research: Employed in studies investigating the metabolism, distribution, and long-term health effects of specific PCB congeners.
• Waste and Material Analysis: Used for calibrating equipment and validating methods in the analysis of PCBs in industrial wastes, transformer oils, and other legacy materials.
• Quality Control and Assurance: Acts as a critical component in the quality control protocols of laboratories performing PCB analysis, ensuring accuracy and reproducibility of results.
• Regulatory Method Development: Essential for developing, validating, and accrediting analytical methods according to EPA, EU, and other international standards.
