Ipragliflozin Impurity 13 (CAS 1922933-61-6) is a certified pharmaceutical impurity reference standard with the molecular formula C21H21FO6S and a molecular weight of 420.45 g/mol.
Based on its molecular formula C21H21FO6S, Ipragliflozin Impurity 13 contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 420.45 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).
As a certified reference material (CRM), Ipragliflozin Impurity 13 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
