Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 328.41 g/mol gives Dibenzo[b,k]chrysene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Dibenzo[b,k]chrysene (CAS 217-54-9), molecular formula C26H16 and molecular weight 328.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Dibenzo[b,k]chrysene (C26H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 328.41 g/mol, it falls into the moderately-high-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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Dibenzo[b,k]chrysene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
