Description

2,2',3,4,4',5,5'-Heptachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance as a critical reference standard and analytical standard for environmental testing and toxicological research. It is primarily needed by analytical laboratories, environmental monitoring agencies, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method development.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the quantification of PCB congeners in soil, water, sediment, and biota samples.
• Toxicological Research: Serves as a precise standard in studies investigating the metabolism, bioaccumulation, and specific toxic effects of heptachlorinated biphenyls.
• Regulatory Compliance Testing: Essential for calibrating equipment and validating methods to ensure compliance with global regulations like the Stockholm Convention on POPs, EPA methods (e.g., 8082), and other international standards.
• Food and Feed Safety: Employed in the analysis of PCB residues in food products, animal feed, and edible oils to meet safety regulations.
• Waste and Remediation Monitoring: Used to accurately assess PCB contamination levels at industrial sites and monitor the effectiveness of remediation efforts.
• Method Development and Validation: A critical component for developing new analytical techniques (GC-MS, GC-ECD, HRGC/HRMS) and for the routine quality control of laboratory procedures.
• Instrument Calibration: Provides a high-purity standard for the calibration of chromatographic systems to ensure accurate and reproducible results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). This material is light-sensitive (store away from light) and should be handled with appropriate precautions for strong acids/organic solvents. Keep container tightly sealed when not in use to maintain purity and stability.
