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 as a critical analytical standard and reference material for environmental monitoring and toxicological research. It is essential for laboratories and research institutions focused on legacy pollutant analysis, method development, and regulatory compliance testing.

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-specific material for studying the metabolism, distribution, and health effects of PCBs in model organisms.
• Quality Control and Assurance: Employed as a certified reference material (CRM) or internal standard to ensure accuracy and precision in laboratory testing protocols for persistent organic pollutants (POPs).
• Regulatory Compliance Testing: Critical for laboratories performing analysis to comply with global regulations (e.g., Stockholm Convention, EPA methods) concerning PCB monitoring and remediation.
• Method Development and Proficiency Testing: Used by method developers and providers of proficiency testing schemes to challenge and verify analytical techniques for complex matrices.
