Description

2,2',3,4,6'-Pentachlorobiphenyl is a specific, high-purity congener of the polychlorinated biphenyl (PCB) family, identified by the CAS registry number 73575-57-2. This compound is of significant importance as a critical analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and environmental agencies involved in the precise quantification and study of PCB contamination in various matrices.

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for calibrating equipment like GC-MS and HPLC in the analysis of soil, water, and sediment samples.
• Toxicological and Metabolic Research: Used in scientific studies to investigate the biological fate, metabolic pathways, and toxic effects of specific PCB congeners.
• Food and Feed Safety Testing: Serves as a critical standard in laboratories ensuring compliance with maximum residue levels (MRLs) for PCBs in the food chain.
• Industrial Hygiene Monitoring: Employed in the calibration of air sampling and analysis methods to monitor workplace exposure in legacy industrial sites.
• Quality Control and Method Validation: Essential for laboratories to validate analytical methods, perform proficiency testing, and ensure the accuracy of internal quality control protocols.
• Regulatory Compliance and Forensics: Used by government and contract labs to enforce environmental regulations and in forensic source identification of PCB mixtures.
