Description

2,2',3,4,5'-Pentachlorobiphenyl CAS NO 38380-02-8 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 standard in environmental testing and research. It is essential for laboratories and industries involved in the monitoring, analysis, and remediation of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in pollutant detection.
• Toxicological and Ecotoxicological Research: Serves as a precise congener for studying the environmental fate, bioaccumulation, and toxic effects of PCBs.
• Regulatory Compliance Testing: Used by testing laboratories to validate methods and ensure accuracy in monitoring programs for compliance with international regulations (e.g., Stockholm Convention, EPA methods).
• Food and Feed Safety Testing: Employed as a standard in the analysis of PCB residues in food products, animal feed, and edible oils to ensure safety standards.
• Material and Waste Analysis: Applied in the characterization of PCB content in industrial wastes, transformer oils, and contaminated soils/sediments.
• Method Development and Proficiency Testing: Critical for developing new analytical methodologies and for use in inter-laboratory comparison studies to ensure data quality.

Quality Control

Our high-purity reference standards are produced and verified under strict quality management protocols. Each batch is characterized using advanced analytical techniques including GC-MS and HPLC to ensure identity, purity, and stability. A comprehensive Certificate of Analysis (COA) is provided, detailing the certified purity, analytical methods, and traceability. 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 place at a controlled room temperature (typically 15-25°C). For long-term stability, storage at 2-8°C is recommended. Keep the container sealed to prevent contamination and moisture absorption.
