Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 572.60 g/mol gives Ipragliflozin Impurity N3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ipragliflozin Impurity N3 (CAS 1034305-21-9) is a certified pharmaceutical impurity reference standard with the molecular formula C29H29FO9S and a molecular weight of 572.60 g/mol.
The molecular framework of Ipragliflozin Impurity N3 (C29H29FO9S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
