Compared with other compounds in its class, the molecular weight of 498.54 g/mol gives Omarigliptin Impurity 12 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Omarigliptin Impurity 12 (CAS 1819364-05-0) is a certified pharmaceutical impurity reference standard with the molecular formula C22H28F2N4O5S and a molecular weight of 498.54 g/mol.
Omarigliptin Impurity 12 (C22H28F2N4O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Omarigliptin Impurity 12 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.
