Description
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.
Uridine Impurity 10 Disodium Salt (CAS 91183-98-1) is a certified pharmaceutical impurity reference standard with the molecular formula C17H25N3O17P2Na and a molecular weight of 628.33 g/mol.
Based on its molecular formula C17H25N3O17P2Na, Uridine Impurity 10 Disodium Salt contains a flavonoid core, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 628.33 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).
As a certified reference material (CRM), Uridine Impurity 10 Disodium Salt 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.
