Description

2,4',5-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 compound is essential for ensuring accuracy and traceability in sophisticated mass spectrometry and chromatography-based analyses. It is primarily required by analytical laboratories, environmental testing facilities, and research institutions engaged in the quantification and fate-tracking of PCB congeners in complex matrices.

Application

• Internal Standard for Mass Spectrometry (MS): Used as a quantitative reference in GC-MS and LC-MS/MS methods for the analysis of PCBs in environmental, food, and biological samples.
• Environmental Monitoring: Critical for the accurate quantification of PCB contamination in soil, sediment, water, and air samples to comply with regulatory standards.
• Food Safety Testing: Employed in the analysis of PCBs in food products, including fish, dairy, and oils, to monitor for bioaccumulation and ensure consumer safety.
• Metabolic and Degradation Studies: Serves as a stable-isotope tracer in research investigating the metabolic pathways, environmental degradation, and toxicokinetics of PCB congeners.
• Method Development and Validation: A key component in developing, calibrating, and validating new analytical protocols for PCB detection and quantification.
• Quality Assurance/Quality Control (QA/QC): Used in laboratory proficiency testing and as a spike recovery standard to verify the accuracy and precision of analytical results.
