103408-45-3 M1G Pyrimido[1,2-a]purin-10(1H)-one Pyrimido[1,2-a]purin-10(3H)-one CAS 103408-45-3 chemical structure

Description

Based on its molecular formula C8H5N5O, 103408-45-3 M1G Pyrimido[1,2-a]purin-10(1H)-one Pyrimido[1,2-a]purin-10(3H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.16 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).
