21889-33-8 3,5-Bis(methoxycarbonyl)-2,6,-dimethyl-4-(2-aminophenyl)-1,4-dihydropyridine 3,5-Pyridinedicarboxylic acid, 4-(2-aminophenyl)-1,4-dihydro-2,6-dimethyl-, dimethyl ester Bmcdapp CAS 21889-33-8

Description

The molecular framework of 21889-33-8 3,5-Bis(methoxycarbonyl)-2,6,-dimethyl-4-(2-aminophenyl)-1,4-dihydropyridine 3,5-Pyridinedicarboxylic acid, 4-(2-aminophenyl)-1,4-dihydro-2,6-dimethyl-, dimethyl ester Bmcdapp (C17H20N2O4) is characterized by a flavonoid core, an amide 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 supplies 21889-33-8 3,5-Bis(methoxycarbonyl)-2,6,-dimethyl-4-(2-aminophenyl)-1,4-dihydropyridine 3,5-Pyridinedicarboxylic acid, 4-(2-aminophenyl)-1,4-dihydro-2,6-dimethyl-, dimethyl ester Bmcdapp (CAS 21889-33-8), a certified reference material (molecular formula C17H20N2O4, MW 316.35 g/mol) for analytical method development and quality control.
