Description

2,2',3,3',4,5,5',6,6'-Nonachlorobiphenyl is a highly chlorinated congener of the polychlorinated biphenyl (PCB) family, identified by the CAS registry number 52663-77-1. This compound is of significant importance for analytical and research purposes, particularly in environmental monitoring, toxicology studies, and the development of reference standards. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions focused on persistent organic pollutant (POP) analysis, regulatory compliance, and method validation.

Application

• Analytical Reference Standard: Used as a certified reference material (CRM) for the calibration of instruments and validation of analytical methods in gas chromatography (GC) and mass spectrometry (MS).
• Environmental Analysis: Serves as a critical standard for the quantification and confirmation of PCB congeners in soil, water, sediment, and biota samples to assess contamination levels.
• Toxicological Research: Employed in scientific studies to investigate the environmental fate, bioaccumulation, and specific toxicological effects of highly chlorinated PCB congeners.
• Quality Control & Assurance: Utilized by testing laboratories to perform internal quality control checks and ensure the accuracy and precision of PCB congener analysis.
• Regulatory Compliance Testing: Essential for laboratories conducting analysis to comply with international regulations concerning POPs, such as the Stockholm Convention.
• Method Development: Acts as a key component in the development and optimization of new analytical protocols for the separation and detection of complex PCB mixtures.
