Description

2,2',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 the analysis of persistent organic pollutants (POPs), ecological impact studies, and the development of remediation technologies.

Application

• Environmental Analysis Reference Standard: Used for the calibration and validation of analytical instruments (GC, GC-MS, HPLC) in the detection and quantification of PCBs in soil, water, sediment, and biota samples.
• Toxicological and Biomedical Research: Serves as a precise congener standard in studies investigating the metabolism, distribution, and chronic health effects of PCBs, including endocrine disruption and carcinogenicity.
• Regulatory Compliance and Method Development: Essential for laboratories performing testing to comply with global regulations (e.g., Stockholm Convention, EPA methods) and for developing new analytical methodologies.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal standard or spike in recovery experiments to ensure the accuracy and precision of analytical data in commercial and regulatory testing labs.
• Forensic and Source Identification Studies: Used to create congener-specific profiles to help trace the source and history of PCB contamination in environmental forensic investigations.
• Educational and Proficiency Testing: Provided to academic institutions and used in laboratory proficiency testing programs to train analysts and ensure inter-laboratory comparability of results.
