Description

2,2',3,4,6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This high-purity reference standard is critical for analytical and research applications, enabling precise identification, quantification, and toxicological study of PCB compounds in environmental and biological samples. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method development.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) or high-purity standard for calibrating analytical instruments like GC-MS and HPLC.
• Environmental Monitoring: Used in the analysis of soil, water, sediment, and air samples to monitor PCB contamination levels and assess environmental impact.
• Food and Feed Safety Testing: Essential for quantifying PCB residues in food products, animal feed, and edible oils to ensure compliance with international safety regulations.
• Toxicological and Biomedical Research: Serves as a precise congener standard for studying the metabolism, distribution, and health effects of PCBs in biological systems.
• Method Development and Validation: Used by laboratories to develop, optimize, and validate new analytical methods for PCB detection and quantification.
• Quality Assurance/Quality Control (QA/QC): Employed in laboratory proficiency testing and internal quality control programs to ensure accuracy and reliability of analytical data.
• Regulatory Compliance Testing: Supports testing mandated by regulations such as the Stockholm Convention, EU POPs Regulation, and various national environmental protection laws.

Quality Control

Our high-purity 2,2',3,4,6-Pentachlorobiphenyl is manufactured and handled under strict quality protocols to ensure identity, purity, and stability. Each batch is rigorously analyzed using chromatographic and spectroscopic techniques, including GC-FID/ECD and GC-MS. A comprehensive Certificate of Analysis (COA) is provided, detailing assay purity, congener-specific identity confirmation, and impurity profiles. Our quality system supports traceability and data integrity for research and regulatory applications.

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). For long-term stability, storage at 2-8°C is recommended. Keep the container tightly sealed in a dry environment to prevent any potential moisture uptake or contamination.
