Ilaprazole Impurity 137 CAS CATO-C4X-1130137 chemical structure

Description

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.

CATO supplies Ilaprazole Impurity 137 (CAS CATO-C4X-1130137), a pharmacopoeial impurity reference standard (molecular formula C7H14O3, MW 146.18 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C7H14O3, Ilaprazole Impurity 137 contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 146.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
