Based on its molecular formula C21H33N4O7PS, ditert-butyl [2,2-dimethyl-4-(6-sulfanylidene-3H-purin-9-yl)-3a,4,6,6a-tetrahydrofuro[3,4-d][1,3]dioxol-6-yl]methyl phosphate contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 516.55 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 ditert-butyl [2,2-dimethyl-4-(6-sulfanylidene-3H-purin-9-yl)-3a,4,6,6a-tetrahydrofuro[3,4-d][1,3]dioxol-6-yl]methyl phosphate (CAS 1375103-71-1), a certified reference material (molecular formula C21H33N4O7PS, MW 516.55 g/mol) for analytical method development and quality control.
