Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 428.65 g/mol gives Empagliflozin Impurity 98 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Empagliflozin Impurity 98 (CAS CATO-C4X-106598) is a certified pharmaceutical impurity reference standard with the molecular formula C17H14ClIO3 and a molecular weight of 428.65 g/mol.
Based on its molecular formula C17H14ClIO3, Empagliflozin Impurity 98 contains a steroid core, a hydroxyl group, an ether linkage, chlorine/iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 428.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
