Chemical Structure
Description
As a certified reference material (CRM), Alogliptin Impurity 15 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.
As a process- or degradation-related impurity, Alogliptin Impurity 15 (CAS CATO-C4X-109915, C18H21N5O2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Alogliptin Impurity 15 (C18H21N5O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
