Description

2,2',3,5',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical reference standard and analytical tool for environmental monitoring, toxicological research, and regulatory compliance testing. It is essential for laboratories and research institutions focused on the identification, quantification, and study of persistent organic pollutants (POPs) in various matrices.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for calibrating equipment and validating methods in the analysis of soil, water, sediment, and air samples for PCB contamination.
• Toxicological and Biomedical Research: Serves as a precise congener standard in studies investigating the metabolism, distribution, and health effects of specific PCB congeners.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories ensuring compliance with maximum residue limits (MRLs) for PCBs in food products, animal feed, and edible oils.
• Waste and Remediation Monitoring: Critical for accurate measurement of PCB congeners in industrial waste, transformer oils, and materials from remediation sites to meet environmental regulations.
• Quality Control and Method Development: Provides a known, high-purity compound for developing, optimizing, and verifying the accuracy and precision of chromatographic (GC, GC-MS, HPLC) analytical methods.
• Regulatory Compliance and Proficiency Testing: Used by testing laboratories to demonstrate competency and generate legally defensible data for global regulations concerning POPs (e.g., Stockholm Convention, EPA methods).
