Description

2,2',3,4',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized in specialized research and analytical chemistry as a critical reference standard for environmental monitoring and toxicological studies. It is essential for laboratories and organizations involved in the analysis of persistent organic pollutants (POPs), regulatory compliance testing, and the development of remediation technologies.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration and validation of analytical instruments like GC-MS and HPLC in testing for PCB contamination in soil, water, and air.
• Toxicological Research: Serves as a specific congener for studying the biochemical pathways, bioaccumulation, and health effects of PCBs in ecological and mammalian models.
• Regulatory Compliance and Method Development: Essential for laboratories performing tests to comply with international 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 analytical procedures to ensure accuracy, precision, and reliability of test results for PCBs.
• Forensic and Source Identification Studies: Aids in chemical fingerprinting to identify the source and history of PCB contamination in environmental forensic investigations.
• Educational and Pharmaceutical Research: Used in academic settings for advanced chemistry education and in specialized pharmaceutical research investigating historical contaminant interactions.
