Description

2,2',3,4,4',6'-Hexachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is of significant interest for analytical and research purposes, particularly in environmental monitoring, toxicology studies, and the development of reference standards. It is primarily required 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 analytical instruments like GC-MS and HPLC in environmental testing.
• Environmental Monitoring: Serves as a critical standard for the quantification and identification of PCB congeners in soil, water, sediment, and air samples to assess contamination levels.
• Toxicological Research: Employed in laboratory studies to investigate the specific biological effects, metabolic pathways, and toxicity profiles of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods to ensure accuracy, precision, and regulatory compliance for PCB analysis.
• Quality Control/Quality Assurance (QC/QA): Used as an internal standard or spike in laboratory QC procedures to verify the performance and reliability of analytical results.
• Regulatory Compliance Testing: Supports testing mandated by regulations such as the Stockholm Convention, EPA methods, and other international directives on POPs.
