Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 514.58 g/mol gives Linagliptin Impurity 111 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Linagliptin Impurity 111 (CAS CATO-C4X-1101111) is a certified pharmaceutical impurity reference standard with the molecular formula C26H30N10O2 and a molecular weight of 514.58 g/mol.
Linagliptin Impurity 111 (C26H30N10O2) 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 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.
As a certified reference material (CRM), Linagliptin Impurity 111 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.
