Chemical Structure

Ilaprazole Impurity 121 CAS 13436-43-6 chemical structure

Description

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.

CATO supplies Ilaprazole Impurity 121 (CAS 13436-43-6), a pharmacopoeial impurity reference standard (molecular formula C5H8O2, MW 100.12 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ilaprazole Impurity 121 (C5H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 100.12 g/mol, it falls into the low-molecular-weight range.

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.
