Description

2,3,3',4',6-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of industrial chemicals. This high-purity reference standard is critical for analytical and research applications, enabling precise identification and quantification in complex matrices. It is primarily utilized by environmental testing laboratories, regulatory agencies, and research institutions focused on legacy pollutant analysis, toxicology studies, and method development.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC/MS, GC/ECD, and HPLC systems in the analysis of soil, water, sediment, and biota samples.
• Toxicological Research: Serves as a pure congener for studying the specific metabolic pathways, bioaccumulation potential, and toxic effects (e.g., endocrine disruption) of PCBs.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods to ensure accuracy, precision, and regulatory compliance (e.g., EPA methods).
• Quality Control & Assurance: Employed in laboratory QC protocols as a spike or internal standard to monitor analytical performance and ensure data integrity.
• Regulatory Compliance Testing: Used to confirm the presence and concentration of specific PCB congeners to meet national and international environmental regulations (REACH, TSCA, etc.).
• Forensic and Source Identification: Aids in chemical fingerprinting to trace the source and history of PCB contamination in environmental forensics.
