Description

2,2',3,4',6,6'-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound matters as a critical reference standard and analytical tool for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily needed by analytical laboratories, research institutions, and environmental agencies involved 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 analytical instruments like GC-MS and HPLC to detect and quantify PCBs in soil, water, and air samples.
• Toxicological and Metabolic Research: Serves as a pure congener for studying the specific biological effects, metabolic pathways, and persistence of PCBs in ecological and laboratory models.
• Regulatory Compliance and Method Validation: Essential for validating analytical methods to ensure compliance with international environmental regulations (e.g., EPA, EU directives) concerning PCB monitoring.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories testing for PCB contamination in the food chain to ensure product safety.
• Waste and Remediation Analysis: Used to accurately assess PCB congener profiles in industrial waste, transformer oils, and sites undergoing environmental remediation.
• Quality Control for Manufacturing: Acts as a purity benchmark for chemical suppliers and manufacturers requiring precise congener specifications.
