Chemical Structure

Ipragliflozin Impurity 16 CAS CATO-C4X-188516 chemical structure

Description

Ipragliflozin Impurity 16 (C21H21FO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Ipragliflozin Impurity 16 (CAS CATO-C4X-188516) is a certified pharmaceutical impurity reference standard with the molecular formula C21H21FO5S and a molecular weight of 404.45 g/mol.

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.
