Description

3,4,4'-Trichlorobiphenyl-2',3',5',6'-D4 is a deuterated isotopologue of a polychlorinated biphenyl (PCB), specifically designed for use as an analytical standard. This high-purity, stable isotope-labeled compound is essential for ensuring accuracy and reliability in sophisticated analytical techniques. It is primarily utilized by analytical chemists and researchers in environmental testing, food safety, and forensic toxicology laboratories for precise quantification and method validation.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference in GC-MS and LC-MS/MS analysis of PCBs in complex matrices.
• Environmental Analysis: Used in the detection and quantification of PCB congeners in soil, sediment, water, and air samples to monitor pollution and assess remediation efforts.
• Food and Feed Safety Testing: Enables accurate measurement of PCB contamination levels in food products, animal feed, and edible oils to ensure regulatory compliance.
• Forensic and Clinical Toxicology: Supports investigations into human exposure by providing a reliable standard for analyzing PCBs in biological tissues and fluids.
• Method Development and Validation: Acts as a spike-in control to establish recovery rates, calibration curves, and the precision of new analytical protocols.
• Quality Assurance/Quality Control (QA/QC): Integral to laboratory proficiency testing and the ongoing verification of analytical instrument performance.
