Description

2,3,3',4,5,6-Hexachlorobiphenyl is a specific, high-purity congener of polychlorinated biphenyls (PCBs) used primarily as a critical reference standard and analytical tool. This compound is essential for environmental monitoring, toxicological research, and regulatory compliance testing due to its defined chemical structure. It is a vital material for analytical laboratories, research institutions, and environmental agencies involved in the precise identification and quantification of PCB contaminants.

Application

• Environmental Analysis Reference Standard: Used as a certified reference material (CRM) for the calibration of GC-MS, GC-ECD, and HPLC systems in the analysis of soil, water, sediment, and biota samples.
• Toxicological and Metabolic Studies: Serves as a pure congener for investigating the specific biological effects, metabolic pathways, and persistence of PCBs in ecological and mammalian systems.
• Food and Feed Safety Testing: Employed as an analytical standard in laboratories to ensure compliance with strict international regulations on PCB residues in the food chain.
• Quality Control and Method Development: Essential for validating analytical methods, conducting laboratory proficiency testing, and ensuring the accuracy and precision of PCB testing protocols.
• Regulatory Compliance and Forensics: Used to confirm the presence and concentration of specific PCB congeners for legal and environmental forensic applications.
• Chemical Research and Synthesis: Acts as a building block or intermediate in specialized organic synthesis and chemical research focused on halogenated aromatic compounds.
