Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 416.55 g/mol gives Clascoterone Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Clascoterone Impurity 9 (CAS CATO-C4X-33319) is a certified pharmaceutical impurity reference standard with the molecular formula C25H36O5 and a molecular weight of 416.55 g/mol.
The molecular framework of Clascoterone Impurity 9 (C25H36O5) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Clascoterone Impurity 9 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.
