Description

2,2'3,6,6'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized in specialized research and analytical chemistry as a critical reference standard for environmental monitoring and toxicological studies. It is essential for laboratories and organizations involved in the analysis of persistent organic pollutants (POPs), regulatory compliance testing, and the development of remediation technologies.

Application

• Environmental Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of GC/MS and HPLC systems in the quantification of PCB congeners in soil, water, and biological samples.
• Toxicology and Ecotoxicology Research: Serves as a key reagent in studies investigating the biochemical pathways, metabolic fate, and chronic toxic effects of specific PCB congeners.
• Regulatory Compliance and Method Development: Essential for validating analytical methods to meet international standards (e.g., EPA, EU) for monitoring POPs in industrial effluents and consumer products.
• Forensic Environmental Analysis: Acts as a marker congener in source identification and apportionment studies for PCB contamination in the environment.
• Quality Control/Quality Assurance (QC/QA): Employed in internal laboratory quality control programs to ensure the accuracy and precision of PCB analysis.
• Educational and Pharmaceutical Research: Used in academic settings for advanced chemistry education and in research exploring the structural activity relationships of halogenated aromatics.

Quality Control

Every batch of our 2,2'3,6,6'-Pentachlorobiphenyl is produced and handled under strict quality management protocols to ensure the highest standards of purity and consistency required for analytical and research applications. We provide comprehensive Certificates of Analysis (COA) that detail purity, congener-specific identity confirmation, and trace impurity profiles, typically determined by GC-FID/GC-ECD and confirmed by GC-MS. Our quality system is designed to support GLP (Good Laboratory Practice) and meet the needs of regulatory method validation.

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). For long-term stability, storage at 2-8°C is recommended. Keep away from heat and incompatible materials.
