Description

2,2',3,3',4,6'-Hexachlorobiphenyl 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 tool in environmental and toxicological research. It is essential for laboratories and research institutions focused on legacy pollutant analysis, regulatory compliance testing, and fate/transport studies. The availability of a high-purity, well-characterized standard is fundamental for accurate quantification and risk assessment of PCB contamination in various matrices.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of analytical instruments (GC-MS, GC-ECD) in the detection and quantification of PCBs in soil, water, sediment, and air samples.
• Toxicological Research: Serves as a precise congener-specific standard in studies investigating the biochemical pathways, metabolic fate, and chronic health effects of individual PCB congeners.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories monitoring PCB residues to ensure compliance with strict international food safety regulations (e.g., EU, FDA).
• Waste and Remediation Monitoring: Critical for accurate analysis in sites contaminated with PCBs, enabling effective tracking of remediation efforts and verification of cleanup levels.
• Method Development and Validation: Used by analytical chemists to develop, optimize, and validate new chromatographic and spectroscopic methods for congener-specific PCB analysis.
• Quality Assurance/Quality Control (QA/QC): Acts as a spike or internal standard in laboratory QA/QC protocols to ensure the accuracy, precision, and reliability of analytical data.
