Description

2,2',3,4,5,5',6-Heptachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is essential for laboratories and research institutions focused on persistent organic pollutant (POP) analysis, food safety, and occupational health. The reliable supply of this high-purity congener is fundamental for accurate calibration, method validation, and quality control in trace-level detection.

Application

• Environmental Analysis Reference Standard: Calibration and quantification of PCBs in soil, sediment, water, and air samples for pollution assessment.
• Food and Feed Safety Testing: Used as a certified reference material (CRM) to detect and quantify PCB residues in food products, animal feed, and edible oils.
• Toxicological and Biomedical Research: Serves as a precise congener-specific standard in studies investigating the metabolism, distribution, and health effects of PCBs.
• Regulatory Compliance and Proficiency Testing: Essential for laboratories to validate methods and demonstrate competency in meeting international standards (e.g., EPA, EU) for PCB monitoring.
• Waste and Material Analysis: Used in the characterization of PCB content in industrial wastes, transformer oils, and other contaminated materials.
• Forensic and Source Identification Studies: Aids in chemical fingerprinting to trace the origin and history of PCB contamination in the environment.
