Description

2,3,4',6-Tetrachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It is essential for laboratories and research institutions focused on the analysis of persistent organic pollutants (POPs), environmental forensics, and studying the metabolic pathways and ecological impact of chlorinated aromatics.

Application

• Environmental Analysis Reference Standard: Used for the calibration and validation of analytical instruments (GC-MS, HPLC) in the detection and quantification of PCBs in soil, water, sediment, and biological samples.
• Toxicological and Metabolic Research: Serves as a pure congener for studying the specific toxicokinetics, metabolic degradation pathways, and health effects of tetrachlorobiphenyl isomers.
• Regulatory Compliance and Method Development: Essential for laboratories performing tests to comply with global regulations (e.g., Stockholm Convention, EPA methods) regarding POPs and for developing new analytical methodologies.
• Quality Control and Proficiency Testing: Employed as a known component in quality control samples and inter-laboratory comparison programs to ensure accuracy and consistency in PCB analysis across different facilities.
• Chemical Research and Synthesis: Acts as a building block or intermediate in specialized organic synthesis research focused on halogenated aromatic compounds.
• Forensic and Source Identification Studies: Used as a marker congener in environmental forensics to trace the source and weathering history of PCB contamination in the environment.
