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.
Dapagliflozin Impurity 94 (CAS 83466-88-0) is a certified pharmaceutical impurity reference standard with the molecular formula C4H6O2C2H4O2 and a molecular weight of 146.14 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Dapagliflozin Impurity 94 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
As a certified reference material (CRM), Dapagliflozin Impurity 94 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.
