Description

2,4,4'-Trichlorobiphenyl-2',3',5',6'-D4 is a deuterated analog of a polychlorinated biphenyl (PCB), specifically designed for use as an internal standard in analytical chemistry. This compound is critical for ensuring the accuracy and reliability of quantitative analyses, particularly in environmental monitoring and regulatory compliance testing. It is an essential tool for analytical laboratories, research institutions, and industries requiring precise measurement of PCB contaminants in complex matrices.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference in GC-MS and LC-MS methods for the analysis of PCBs and related environmental pollutants.
• Environmental Analysis: Critical for the accurate quantification of PCB congeners in soil, water, sediment, and air samples to meet regulatory standards.
• Food Safety Testing: Employed in methods to detect and quantify PCB residues in food products, animal feed, and edible oils.
• Forensic and Toxicological Studies: Serves as a stable isotopic tracer in research investigating the metabolism, distribution, and persistence of PCBs in biological systems.
• Method Development and Validation: Essential for developing, calibrating, and validating new analytical protocols for halogenated organic compounds.
• Quality Control/Quality Assurance (QC/QA): Used to monitor analytical performance, correct for instrument variability, and ensure data integrity in high-throughput testing laboratories.
