Description

2,3',4,4',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant importance for analytical reference, environmental monitoring, and toxicological research due to its persistence and bioaccumulative properties. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting studies on persistent organic pollutants (POPs), ecological impact assessments, and regulatory compliance testing.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Monitoring: Serves as a key analyte for the detection and quantification of PCB congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Employed in laboratory studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual PCB congeners.
• Method Development and Validation: Critical for developing, optimizing, and validating new analytical methods for PCB congener-specific analysis in complex matrices.
• Quality Control/Assurance: Used as a spike or internal standard in laboratory QC procedures to ensure accuracy and precision in PCB analysis for regulatory purposes.
• Regulatory Compliance Testing: Essential for testing products and environmental samples to ensure compliance with international regulations like the Stockholm Convention on POPs.

Quality Control

Our high-purity reference materials are produced and handled under strict quality-controlled conditions to ensure batch-to-batch consistency and reliability for critical analytical work. Each batch is characterized using advanced techniques including GC-MS and HPLC to confirm identity and purity. A comprehensive Certificate of Analysis (COA) is provided, detailing the certified purity, analytical methods, and traceability information. We support compliance with ISO 17034 and ISO/IEC 17025 requirements for reference material producers and testing 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 absorption. For long-term storage, consider storing under inert atmosphere at lower temperatures (e.g., -20°C) to maximize stability.
