Description

2,4,5-Trichlorobiphenyl-2',3',4',5',6'-D5 is a deuterated analog of a polychlorinated biphenyl (PCB) congener, 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 and toxicological studies. It is primarily needed by analytical laboratories, environmental testing facilities, and research institutions conducting trace-level detection of PCBs using techniques like GC-MS or LC-MS.

Application

• Internal Standard for Mass Spectrometry: Used as a deuterated internal standard for the precise quantification of 2,4,5-trichlorobiphenyl and related PCB congeners in complex matrices via GC-MS or LC-MS.
• Environmental Analysis: Essential for monitoring and quantifying PCB contamination in soil, water, sediment, and air samples to comply with environmental regulations.
• Food and Feed Safety Testing: Employed in the analysis of PCBs in food products, animal feed, and edible oils to ensure consumer safety and regulatory compliance.
• Toxicology and Metabolism Studies: Serves as a stable-isotope labeled tracer in research investigating the environmental fate, biodegradation, and metabolic pathways of PCBs.
• Quality Control/Assurance: Integral to method development, validation, and routine quality control procedures in analytical laboratories to guarantee data integrity.
• Reference Material: Used for the calibration of analytical instruments and the preparation of certified reference materials (CRMs).
