Description

2,2',3,6'-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of industrial chemicals. This compound is primarily utilized as a critical reference standard and analytical standard for environmental testing, toxicological research, and regulatory compliance monitoring. It serves essential roles for research laboratories, environmental testing facilities, and chemical manufacturers engaged in PCB analysis, method development, and quality control.

Application

• Environmental Analysis Reference Standard: Used for the calibration of GC/MS, GC/ECD, and HPLC systems in the quantification of PCB residues in soil, water, sediment, and biota.
• Toxicological and Metabolic Research: Employed as a pure congener in studies investigating the biological fate, metabolic pathways, and toxic effects of specific PCB structures.
• Method Development and Validation: Serves as a key component in developing, optimizing, and validating analytical methods for PCB congener-specific analysis.
• Quality Control (QC) and Proficiency Testing: Used in the preparation of QC samples and proficiency testing materials to ensure accuracy and reliability in analytical laboratories.
• Regulatory Compliance Testing: Essential for laboratories performing testing to comply with international regulations (e.g., EPA, EU) concerning PCB monitoring and reporting.
• Chemical Synthesis Intermediate: Can be used as a building block or precursor in specialized organic synthesis for research purposes.
