Description

2,2',4,5,6'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is primarily utilized in research and analytical chemistry as a critical reference standard for environmental monitoring and toxicological studies. It is essential for laboratories and institutions involved in the analysis of persistent organic pollutants (POPs), regulatory compliance testing, and the development of remediation technologies.

Application

• Environmental Analysis Reference Standard: Used for the calibration and quantification of PCBs in soil, water, sediment, and biota samples via GC-MS or GC-ECD.
• Toxicological Research: Serves as a pure congener for studying the specific biological effects, metabolic pathways, and persistence of pentachlorobiphenyl isomers.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods in accordance with EPA, EU, and other international standards.
• Quality Control/Quality Assurance (QC/QA): Employed as an internal or external standard to ensure accuracy and precision in commercial and regulatory testing laboratories.
• Forensic and Source Identification: Aids in chemical fingerprinting to trace the source and history of PCB contamination in environmental forensic investigations.
• Educational and Reference Material: Used in academic and training settings to teach advanced analytical techniques for halogenated organic compounds.
