Description

2,3,5,6-Tetrachlorobiphenyl-2',3',4',5',6'-D5 is a deuterated internal standard critical for high-precision analytical quantification. This compound is essential for ensuring accurate and reliable measurements in complex environmental and biological matrices. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting trace-level analysis of polychlorinated biphenyls (PCBs).

Application

• Internal Standard for GC/MS and LC-MS/MS Analysis: Used for the precise quantification of specific PCB congeners in environmental samples like soil, water, and sediment.
• Metabolite Tracing in Biomedical Research: Enables the study of PCB metabolism, distribution, and toxicokinetics in biological systems.
• Quality Control in Food Safety Testing: Serves as a reference standard in the analysis of PCB contamination in food and feed products.
• Method Development and Validation: Critical for establishing and verifying the accuracy of new analytical protocols for halogenated organic compounds.
• Forensic and Regulatory Analysis: Supports compliance testing and source identification in investigations related to persistent organic pollutants (POPs).
• Calibration Standard Preparation: Used to create calibration curves with high isotopic purity, correcting for instrument variability and matrix effects.
