Description
As a certified reference material (CRM), Saxagliptin Impurity 89 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.
Saxagliptin Impurity 89 (CAS CATO-C4X-104989) is a certified pharmaceutical impurity reference standard with the molecular formula C25H32F3N3O5 and a molecular weight of 511.53 g/mol.
Based on its molecular formula C25H32F3N3O5, Saxagliptin Impurity 89 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 511.53 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).
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.
