Propafenone Impurity 26 CAS CATO-C4X-132226

Description

Compared with other compounds in its class, the molecular weight of 395.45 g/mol gives Propafenone Impurity 26 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Propafenone Impurity 26 (CAS CATO-C4X-132226) is a certified pharmaceutical impurity reference standard with the molecular formula C23H25NO5 and a molecular weight of 395.45 g/mol.

Based on its molecular formula C23H25NO5, Propafenone Impurity 26 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 395.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Propafenone Impurity 26 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.
