Ilaprazole Impurity 147 CAS CATO-C4X-1130147

Description

Compared with other compounds in its class, the molecular weight of 456.45 g/mol gives Ilaprazole Impurity 147 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ilaprazole Impurity 147 (CAS CATO-C4X-1130147), a pharmacopoeial impurity reference standard (molecular formula C24H20N6O4, MW 456.45 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ilaprazole Impurity 147 (C24H20N6O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 456.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
