Chemical Structure
Description
Based on its molecular formula C18H24N2O4S, 74259-08-8 B6B1RRA3XL Desacetyl-alacepril L-Phenylalanine, N-(1-(3-mercapto-2-methyl-1-oxopropyl)-L-prolyl)-, (S)- DU-1227 UNII-B6B1RRA3XL contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 364.46 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).
