Chemical Structure

Dapagliflozin Impurity 98 CAS CATO-C4X-113898 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 394.68 g/mol gives Dapagliflozin Impurity 98 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Dapagliflozin Impurity 98 (CAS CATO-C4X-113898) is a certified pharmaceutical impurity reference standard with the molecular formula C15H34O6Si3 and a molecular weight of 394.68 g/mol.

The molecular framework of Dapagliflozin Impurity 98 (C15H34O6Si3) 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.
