Chemical Structure

{[(4aR,6R,7R,7aR)-6-{6-Amino-8-[(4-chlorophenyl)sulfanyl]-9H-purin-9-yl}-7-methoxy-2-oxo-hexahydro-2λ-furo[3,2-d][1,3,2]dioxaphosphinin-2-yl]oxy}methyl acetate CAS 1152197-23-3 chemical structure

Description

Based on its molecular formula C20H21ClN5O8PS, {[(4aR,6R,7R,7aR)-6-{6-Amino-8-[(4-chlorophenyl)sulfanyl]-9H-purin-9-yl}-7-methoxy-2-oxo-hexahydro-2λ-furo[3,2-d][1,3,2]dioxaphosphinin-2-yl]oxy}methyl acetate contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 557.90 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).

CATO supplies {[(4aR,6R,7R,7aR)-6-{6-Amino-8-[(4-chlorophenyl)sulfanyl]-9H-purin-9-yl}-7-methoxy-2-oxo-hexahydro-2λ-furo[3,2-d][1,3,2]dioxaphosphinin-2-yl]oxy}methyl acetate (CAS 1152197-23-3), a certified reference material (molecular formula C20H21ClN5O8PS, MW 557.90 g/mol) for analytical method development and quality control.
