Description

2,3,4-Trichlorobiphenyl-2',3',4',5',6'-D5 is a deuterated isotopologue of a polychlorinated biphenyl (PCB) congener, specifically designed for use as an internal standard in analytical chemistry. This compound is critical for ensuring the accuracy and precision of quantitative analyses, particularly in environmental and toxicological studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting high-sensitivity mass spectrometry (MS) and gas chromatography (GC) for the detection and quantification of PCBs.

Application

• Internal Standard for Mass Spectrometry: Used as a deuterated internal standard in GC-MS and LC-MS methods for the accurate quantification of non-labeled PCB congeners in complex matrices.
• Environmental Analysis: Essential for monitoring PCB contamination in soil, water, sediment, and air samples to comply with environmental regulations.
• Food and Feed Safety Testing: Employed in the analysis of PCBs in food products, animal feed, and edible oils to ensure consumer safety and regulatory compliance.
• Toxicology and Metabolism Studies: Serves as a stable-isotope tracer in research investigating the environmental fate, metabolic pathways, and toxicokinetics of PCBs.
• Method Development and Validation: A key reagent for developing, calibrating, and validating analytical methods due to its defined isotopic purity and structural similarity to target analytes.
• Quality Control/Quality Assurance (QC/QA): Integral to laboratory QC protocols, including recovery studies and the assessment of analytical method performance.
