Chemical Structure

Ilaprazole Impurity 27 CAS CATO-C4X-113027 chemical structure

Description

The occurrence of Ilaprazole Impurity 27 is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Ilaprazole Impurity 27 (CAS CATO-C4X-113027, C18H12N4OS) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

The molecular framework of Ilaprazole Impurity 27 (C18H12N4OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

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.
