Benzo[a]Pyrene-d12
![Chemical structure of Benzo[a]Pyrene-d12, CAS 63466-71-7](/assets/structures/CPAH111526.webp)
Polycyclic aromatic hydrocarbon monitoring commonly relies on deuterated internal standards, and Benzo[a]Pyrene-d12 is the fully deuterated analogue of benzo[a]pyrene, the five-ring compound widely used as a marker in environmental, food and consumer-product testing. Twelve deuterium atoms give the standard a mass shift sufficient for mass spectrometric discrimination while keeping its chromatographic behaviour close to that of the native analyte, which is what makes it useful for isotope-dilution quantification. Laboratories use it to compensate for losses during extraction and cleanup, to control injection and ionisation variability, and to support validation of GC-MS/MS or LC-MS/MS methods for PAH determination in complex matrices. It is a yellow to dark yellow solid with the formula C20D12 and a molecular weight of 264.38. Storage at 2°C to 8°C is advised, and shipping is arranged at room temperature. Listed pack sizes include 5 mg, 10 mg, 25 mg, 50 mg and 200 mg. Ask for a quotation or the supporting documentation.
