Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.31 g/mol gives 5-Methylbenzo[c]phenanthrene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Methylbenzo[c]phenanthrene (CAS 652-04-0) is a high-purity analytical reference standard with the molecular formula C19H14 and a molecular weight of 242.31 g/mol.
The molecular framework of 5-Methylbenzo[c]phenanthrene (C19H14) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 5-Methylbenzo[c]phenanthrene 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.
