Testosterone Impurity N9 CAS 162890-98-4

Description

Compared with other compounds in its class, the molecular weight of 514.78 g/mol gives Testosterone Impurity N9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Testosterone Impurity N9 (CAS 162890-98-4) is a certified pharmaceutical impurity reference standard with the molecular formula C33H54O4 and a molecular weight of 514.78 g/mol.

Testosterone Impurity N9 (C33H54O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Testosterone Impurity N9 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.
