Description

4-Chlorobiphenyl-D5 is a deuterium-labeled analog of 4-chlorobiphenyl, a key compound in the polychlorinated biphenyl (PCB) family. This stable isotope-labeled standard is essential for ensuring the accuracy and reliability of analytical methods, particularly in trace-level detection and quantification. It is critically needed by analytical laboratories, environmental testing facilities, and research institutions engaged in method development, quality control, and regulatory compliance testing for persistent organic pollutants.

Application

• Internal Standard for Mass Spectrometry: Primary use as a quantitative internal standard in GC-MS and LC-MS/MS analysis for PCBs.
• Environmental Analysis: Calibration and recovery studies in the testing of soil, water, sediment, and air samples for PCB contamination.
• Food Safety Testing: Used in the accurate quantification of PCB residues in food and feed products to ensure regulatory compliance.
• Clinical and Biological Research: Tracing and metabolic studies of PCBs and related chlorinated hydrocarbons in biological matrices.
• Method Development and Validation: Critical for developing, optimizing, and validating analytical methods according to ISO, EPA, and other international standards.
• Quality Assurance/Quality Control (QA/QC): Serves as a reference material in laboratory proficiency testing and for verifying analytical instrument performance.
