Nicardipine Impurity 33 CAS CATO-C4X-171033

Description

Compared with other compounds in its class, the molecular weight of 404.37 g/mol gives Nicardipine Impurity 33 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Nicardipine Impurity 33 (CAS CATO-C4X-171033), a pharmacopoeial impurity reference standard (molecular formula C19H20N2O8, MW 404.37 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C19H20N2O8, Nicardipine Impurity 33 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 404.37 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), Nicardipine Impurity 33 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.
