Description

2,3',4,6-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a 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, environmental forensics, and the development of remediation strategies.

Application

• Environmental Analysis Reference Standard: Primary use as a certified standard for the quantification and identification of PCB congeners in soil, water, sediment, and biological samples via GC-MS or HPLC.
• Toxicological and Biomedical Research: Used in studies to investigate the metabolism, distribution, and specific toxic effects (e.g., endocrine disruption, neurotoxicity) of chlorinated biphenyls.
• Regulatory Compliance and Method Development: Serves as a calibrant for methods validating compliance with international regulations like the Stockholm Convention on POPs, EPA methods, and other environmental directives.
• Forensic and Source Identification: Aids in chemical fingerprinting to trace the source and history of PCB contamination in environmental samples due to its specific congener profile.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike recovery standard to ensure the accuracy and precision of analytical laboratory data.
• Material and Product Testing: Used to test the efficiency of degradation technologies or adsorption materials designed to remove PCBs from contaminated streams.
