Description

2,3',4,5',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 reagent in environmental testing and research. It serves essential roles for laboratories and organizations involved in monitoring, regulatory compliance, and toxicological studies. The material is indispensable for calibrating equipment and validating methods in the analysis of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification and identification of PCB congeners in soil, water, sediment, and biota samples.
• Regulatory Compliance Testing: Essential for laboratories conducting analysis to comply with global regulations (e.g., EPA, EU POPs Regulation) concerning PCB contamination.
• Toxicological and Ecotoxicological Research: Serves as a pure congener for studying the specific environmental fate, metabolic pathways, and toxic effects of PCBs.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods such as GC-MS, GC-ECD, and HRGC/HRMS for PCB analysis.
• Quality Control/Quality Assurance (QC/QA): Employed in laboratory proficiency testing and as an internal standard to ensure accuracy and precision in analytical data.
• Food and Feed Safety Monitoring: Used in the analysis of PCB residues to ensure safety standards are met in the food supply chain.
• Waste and Remediation Site Characterization: Aids in the fingerprinting and source identification of PCB mixtures at contaminated sites.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is light-sensitive (store away from light) and should be kept in its original packaging or an amber glass vial. For long-term stability, storage under an inert atmosphere such as nitrogen is recommended. Keep away from strong acids and organic solvents.
