Description
CATO manufactures Rebamipide Impurity 50 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies Rebamipide Impurity 50 (CAS CATO-C4X-152350), a pharmacopoeial impurity reference standard (molecular formula C10H9Br2NO2, MW 334.99 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C10H9Br2NO2, Rebamipide Impurity 50 contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 334.99 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
