Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 370.79 g/mol gives Rebamipide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Rebamipide (CAS 90098-04-7) is a high-purity analytical reference standard with the molecular formula C19H15ClN2O4 and a molecular weight of 370.79 g/mol.
The molecular framework of Rebamipide (C19H15ClN2O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Rebamipide 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.
