Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 264.38 g/mol gives Benzo[e]pyrene-d12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Benzo[e]pyrene-d12 (CAS 205440-82-0), molecular formula C20D12 and molecular weight 264.38 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Benzo[e]pyrene-d12 (C20D12) contains deuterium isotope labeling, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 264.38 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
