Ilaprazole Impurity 46 CAS CATO-C4X-113046 chemical structure

Description

CATO supplies Ilaprazole Impurity 46 (CAS CATO-C4X-113046), a pharmacopoeial impurity reference standard (molecular formula C14H12N6S2, MW 328.42 g/mol) used for the identification and quantification of trace impurities in APIs.

Ilaprazole Impurity 46 (C14H12N6S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
