Description

2,2',3,4,4',6-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. 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

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC.
• Environmental Analysis: Quantification and confirmation of PCB congeners in soil, water, sediment, and air samples for environmental impact assessments.
• Food and Feed Safety Testing: Used in methods to detect and quantify PCB residues to ensure compliance with food safety regulations.
• Toxicological Research: Serves as a precise standard in studies investigating the metabolism, distribution, and health effects of specific PCB congeners.
• Quality Control and Method Validation: Essential for developing, validating, and maintaining the accuracy and precision of laboratory testing protocols for PCBs.
• Regulatory Compliance and Proficiency Testing: Used by laboratories to demonstrate competency and comply with international standards (e.g., EPA, EU) for POPs monitoring.
