Chemical Structure

Oxiracetam Impurity 14 CAS 24587-49-3 chemical structure

Description

The occurrence of Oxiracetam Impurity 14 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Oxiracetam Impurity 14 (CAS 24587-49-3), a pharmacopoeial impurity reference standard (molecular formula C4H6O3, MW 102.09 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Oxiracetam Impurity 14 (C4H6O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.
