Description

3,4',5-Trichlorobiphenyl-2',3',5',6'-D4 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 achieving accurate quantification and minimizing matrix effects in sensitive detection methods. It is an essential tool for researchers and quality control laboratories in environmental monitoring, food safety, and regulatory compliance sectors who require definitive analysis of PCB contaminants.

Application

• Internal Standard for Mass Spectrometry: Primary use as a quantitative internal standard in GC-MS and LC-MS/MS analysis of PCBs.
• Environmental Analysis: Accurate measurement of PCB congeners in soil, sediment, water, and air samples for pollution studies and site remediation.
• Food and Feed Safety Testing: Quantification of PCB residues in agricultural products, seafood, and animal feed to ensure regulatory compliance.
• Biomedical and Toxicological Research: Used in metabolic studies, exposure assessment, and understanding the environmental fate of halogenated aromatics.
• Quality Assurance/Quality Control (QA/QC): Implementation in laboratory method development, validation, and proficiency testing programs.
• Waste and Industrial Effluent Monitoring: Tracking PCB contamination from industrial sources and in waste treatment processes.
