Description
CATO supplies Ipragliflozin Impurity 11 (CAS CATO-C4X-188511), a pharmacopoeial impurity reference standard (molecular formula C21H21FO5S, MW 404.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ipragliflozin Impurity 11 (C21H21FO5S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 404.45 g/mol, it falls into the moderately-high-molecular-weight range. 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.
As a certified reference material (CRM), Ipragliflozin Impurity 11 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.
