Description

3,5-Dichlorobiphenyl-2',3',4',5',6'-D5 is a deuterated analog of a polychlorinated biphenyl (PCB) congener, specifically designed for use as an internal standard in analytical chemistry. This high-purity, isotopically labeled compound is critical for ensuring the accuracy and reliability of quantitative analyses in complex matrices. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in trace-level detection and method validation for persistent organic pollutants.

Application

• Internal Standard for Mass Spectrometry (MS): Essential for quantitative analysis via GC-MS or LC-MS/MS, correcting for instrument variability and matrix effects in PCB analysis.
• Environmental Monitoring and Analysis: Used in the accurate quantification of PCB congeners in soil, water, sediment, and air samples to assess contamination levels and comply with regulatory limits.
• Food and Feed Safety Testing: Employed in methods to detect and quantify PCB residues in food products, animal feed, and edible oils to ensure consumer safety.
• Clinical and Bioanalytical Research: Serves as a stable isotope-labeled standard in metabolomic or exposomic studies investigating PCB accumulation and metabolism in biological tissues.
• Method Development and Validation: A key reagent for developing, optimizing, and validating new analytical protocols for PCB detection, ensuring method robustness and accuracy.
• Quality Control/Quality Assurance (QC/QA): Integral to laboratory QC programs, used to spike samples for recovery studies and to monitor the performance of analytical instruments over time.
