Description

2,2',4,6'-Tetrachlorobiphenyl CAS NO 68194-04-7 is a specific, high-purity polychlorinated biphenyl (PCB) congener essential for research, analytical, and regulatory applications. This compound serves as a critical reference standard for environmental monitoring, toxicological studies, and the calibration of analytical instrumentation. It is primarily required by analytical laboratories, environmental testing facilities, and chemical manufacturers engaged in quality control and method development for persistent organic pollutant (POP) analysis.

Application

• Analytical Reference Standard: Primary use as a certified standard for Gas Chromatography (GC) and Gas Chromatography-Mass Spectrometry (GC-MS) in environmental analysis.
• Environmental Monitoring: Calibration and quantification of PCBs in soil, water, sediment, and air samples to comply with global regulatory frameworks.
• Toxicological Research: Used in studies to understand the metabolism, bioaccumulation, and specific toxic effects of individual PCB congeners.
• Method Development & Validation: Essential for developing, optimizing, and validating analytical methods in accredited laboratories.
• Quality Control (QC) Material: Serves as a system suitability check and internal standard in high-throughput testing laboratories.
• Regulatory Compliance Testing: Used for testing products and materials to ensure they meet restrictions on PCBs under regulations like TSCA, POPs, and REACH.
• Forensic Analysis: Aiding in the source identification and fingerprinting of PCB mixtures in environmental forensic investigations.
• Educational & Research: Supplied to academic and institutional research programs focused on environmental chemistry and pollutant fate.
