Description

Benzo[E]Pyrene-D12 is a deuterated internal standard of the polycyclic aromatic hydrocarbon (PAH) Benzo[e]pyrene, where twelve hydrogen atoms are replaced with deuterium. This isotopic labeling is critical for ensuring the highest accuracy and reliability in quantitative mass spectrometry analysis. It is an essential analytical standard for environmental, food safety, and toxicology laboratories requiring precise measurement of PAH contamination.

Application

• Quantitative Mass Spectrometry (MS): Serves as a stable isotope-labeled internal standard for the accurate quantification of Benzo[e]pyrene via GC-MS or LC-MS/MS, correcting for analyte loss during sample preparation and instrument variability.
• Environmental Analysis: Used in the testing of soil, water, and air particulate matter for PAH pollutants to meet regulatory environmental monitoring standards.
• Food and Feed Safety Testing: Essential for the analysis of PAHs in smoked foods, edible oils, and other foodstuffs to ensure compliance with food safety regulations like EU 1881/2006.
• Toxicology and Metabolic Studies: Employed in research to study the metabolism, distribution, and biological fate of Benzo[e]pyrene in vitro and in vivo.
• Method Development and Validation: A key reagent for developing, optimizing, and validating new analytical methods for PAH detection with high precision.
• Quality Control and Assurance: Used as a reference material in laboratory proficiency testing and for the calibration of analytical instruments in commercial testing labs.
