Chemical Structure

(2R,3S,5R)-5-(2-Amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-2-(((hydroxy(phosphonooxy)phosphoryl)oxy)methyl)tetrahydrofuran-3-yl 2-(methylamino)benzoate CAS 127383-33-9 chemical structure

Description

The molecular framework of (2R,3S,5R)-5-(2-Amino-6-oxo-3,6-dihydro-9H-purin-9-yl)-2-(((hydroxy(phosphonooxy)phosphoryl)oxy)methyl)tetrahydrofuran-3-yl 2-(methylamino)benzoate (C18H22N6O11P2) is characterized by a flavonoid core, an amide group, a phosphate ester 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).
