Oxymetazoline Impurity 14 CAS 478011-12-0

Description

Compared with other compounds in its class, the molecular weight of 178.27 g/mol gives Oxymetazoline Impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Oxymetazoline Impurity 14 (CAS 478011-12-0) is a certified pharmaceutical impurity reference standard with the molecular formula C12H18O and a molecular weight of 178.27 g/mol.

The molecular framework of Oxymetazoline Impurity 14 (C12H18O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring 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 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 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), Oxymetazoline Impurity 14 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.
