Description

Hexachlorobiphenyl is a specific congener within the polychlorinated biphenyl (PCB) family, characterized by the substitution of six chlorine atoms on the biphenyl structure. This compound is of significant importance for research, analytical, and regulatory compliance purposes, particularly in environmental monitoring and toxicology studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, method development, and calibration standards.

Application

• Analytical Reference Standard: Serves as a critical certified reference material (CRM) for the quantitative analysis of PCBs in environmental samples via GC-MS or GC-ECD.
• Environmental Monitoring: Used in the calibration and quality control procedures for testing soil, sediment, water, and biota for PCB contamination as per EPA and international methods.
• Toxicological Research: Employed in scientific studies to investigate the specific biological effects, metabolic pathways, and environmental fate of hexachlorinated biphenyl congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating new analytical techniques for the detection and quantification of PCBs.
• Regulatory Compliance Testing: Used by commercial and government laboratories to ensure compliance with national and international regulations (e.g., Stockholm Convention, EU directives) concerning POPs.
• Forensic Analysis: Aids in chemical fingerprinting and source identification in cases of environmental pollution incidents involving PCBs.

Quality Control

Our high-purity Hexachlorobiphenyl is manufactured and handled under strict quality protocols to ensure identity, purity, and stability for critical analytical applications. Each batch is rigorously tested using advanced chromatographic and spectroscopic techniques. A comprehensive Certificate of Analysis (COA) is provided, detailing purity, congener-specific identity confirmation, and levels of any relevant impurities, supporting traceability and data integrity for GLP/GMP compliant laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep the container sealed to prevent contamination and moisture uptake. For long-term stability, storage under inert atmosphere is recommended.
