Description

2,3,4,6-Tetrachlorobiphenyl is a specific, high-purity congener of the polychlorinated biphenyl (PCB) family, identified by CAS NO 54230-22-7. This compound is of significant importance as a critical analytical standard and reference material for environmental monitoring, toxicological research, and regulatory compliance testing. It is primarily required by analytical laboratories, research institutions, and environmental agencies engaged in the precise quantification and study of PCB contamination in various matrices.

Application

• Environmental Analysis Standard: Used as a certified reference material (CRM) for calibrating equipment and validating methods in the analysis of soil, water, and sediment samples for PCB contamination.
• Toxicological Research: Serves as a precise congener standard in studies investigating the metabolism, environmental fate, and specific toxic effects of individual PCB compounds.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories to ensure compliance with strict regulatory limits for PCBs in food products, animal feed, and edible oils.
• Quality Control and Method Development: Essential for the development, verification, and ongoing quality assurance of chromatographic methods (GC-MS, GC-ECD) used in commercial and regulatory testing labs.
• Industrial Hygiene Monitoring: Used to calibrate equipment for workplace air monitoring and occupational exposure assessment in industries dealing with historical PCB-containing materials.
