Description
Vildagliptin Impurity 95 (CAS CATO-C4X-110095) is a certified pharmaceutical impurity reference standard with the molecular formula C7H7Cl3N2O and a molecular weight of 241.50 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Vildagliptin Impurity 95 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 241.50 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Vildagliptin Impurity 95 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.
