Oxymetazoline EP Impurity E CAS 55699-10-0

Description

Compared with other compounds in its class, the molecular weight of 217.31 g/mol gives Oxymetazoline EP Impurity E distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Oxymetazoline EP Impurity E (CAS 55699-10-0) is a certified pharmaceutical impurity reference standard with the molecular formula C14H19NO and a molecular weight of 217.31 g/mol.

The molecular framework of Oxymetazoline EP Impurity E (C14H19NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 EP Impurity E 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.
