Chemical Structure

1,7-Dimethylchrysene CAS 15914-24-6 chemical structure

Description

As a certified reference material (CRM), 1,7-Dimethylchrysene 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.

1,7-Dimethylchrysene (CAS 15914-24-6), molecular formula C20H16 and molecular weight 256.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,7-Dimethylchrysene (C20H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 256.34 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).

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.
