Description

2,2',3,3',4',5,5',6-Octachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs). This compound is of significant importance for analytical and research purposes, serving as a critical reference standard for environmental monitoring, toxicological studies, and regulatory compliance testing. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, method development, and quality control.

Application

• Analytical Reference Standard: Primary use as a certified reference material (CRM) for the calibration of analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Monitoring: Quantification and congener-specific analysis of PCBs in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Used in scientific studies to investigate the specific toxicokinetics, metabolic pathways, and health effects of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods for PCB detection and quantification in complex matrices.
• Quality Assurance/Quality Control (QA/QC): Serves as a spike or internal standard to ensure accuracy, precision, and recovery in analytical laboratory procedures.
• Regulatory Compliance Testing: Supports testing to ensure adherence to international regulations concerning POPs, such as the Stockholm Convention.
• Food & Feed Safety Analysis: Used in the analysis of PCB residues in food chains, animal feed, and agricultural products.
• Forensic and Source Identification: Aids in chemical fingerprinting to identify the sources and history of PCB contamination in environmental forensic investigations.
