Chemical Structure

Dibenzo(A,L)Pyrene CAS 191-30-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 302.37 g/mol gives Dibenzo(A,L)Pyrene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dibenzo(A,L)Pyrene (CAS 191-30-0), molecular formula C24H14 and molecular weight 302.37 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Dibenzo(A,L)Pyrene (C24H14) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 302.37 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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(A,L)Pyrene 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.
