Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 318.28 g/mol gives Rebamipide impurity 02 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rebamipide impurity 02 (CAS 1984832-92-9) is a certified pharmaceutical impurity reference standard with the molecular formula C15H14N2O6 and a molecular weight of 318.28 g/mol.
Based on its molecular formula C15H14N2O6, Rebamipide impurity 02 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 318.28 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).
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), Rebamipide impurity 02 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.
