Ethyl (E)-2-(2-((2-(methoxycarbonyl)thiophen-3-yl)amino)vinyl)-5-oxo-5,10-dihydrobenzo[g]quinoline-3-carboxylate (CAS 303995-09-7), molecular formula C24H20N2O5S and molecular weight 448.49 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl (E)-2-(2-((2-(methoxycarbonyl)thiophen-3-yl)amino)vinyl)-5-oxo-5,10-dihydrobenzo[g]quinoline-3-carboxylate (C24H20N2O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. 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).
CATO manufactures Ethyl (E)-2-(2-((2-(methoxycarbonyl)thiophen-3-yl)amino)vinyl)-5-oxo-5,10-dihydrobenzo[g]quinoline-3-carboxylate 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.
