Description

2,2',4,5,5'-Pentachlorobiphenyl-3',4',6'-D3 is a deuterated isotopologue of a specific pentachlorinated biphenyl congener, serving as a critical internal standard for analytical chemistry. This compound is essential for ensuring the accuracy and reliability of quantitative analyses, particularly in complex environmental and biological matrices. It is primarily required by analytical laboratories, research institutions, and regulatory bodies involved in the precise detection and measurement of polychlorinated biphenyl (PCB) contaminants.

Application

• Internal Standard for GC-MS and LC-MS analysis of PCBs in environmental samples (soil, water, sediment).
• Quantitative reference material for method development and validation in analytical laboratories.
• Calibration standard for high-precision mass spectrometry to correct for analyte loss during sample preparation.
• Critical component in isotope dilution techniques for achieving definitive results in regulatory compliance testing.
• Research tool for studying the environmental fate, bioaccumulation, and metabolic pathways of PCB congeners.
• Quality control standard in the production of certified reference materials (CRMs) for PCBs.
