4-Amino-2-methylthio-6-oxo-1,6-dihydropyrimidine and its 1-methyl derivative and 4-amino-2-methoxy-1-methyl-6-oxo-1,6-dihydropyrimidine and its 5-nitroso derivative was written by Low, John N.;Scrimgeour, Sheelagh N.;Egglishaw, Clare;Howie, R. Alan;Moreno-Carretero, Miguel N.;Hueso-Urena, Francisco. And the article was included in Acta Crystallographica, Section C: Crystal Structure Communications in 1994.COA of Formula: C6H9N3OS This article mentions the following:
The structures of 4-amino-2-methylthio-6-oxo-1,6-dihydropyrimidine trihydrate (triclinic, space group P1̅), 4-amino-1-methyl-2-methylthio-6-oxo-1,6-dihydropyrimidine (monoclinic, space group P21/c), 4-amino-2-methoxy-1-methyl-6-oxo-1,6-dihydropyrimidine (monoclinic, space group P21/n) and 4-amino-2-methoxy-1-methyl-5-nitroso-6-oxo-1,6-dihydropyrimidine monohydrate (triclinic, space group P1̅) show that, as has been reported for analogous compounds, there is extensive electron delocalization in the pyrimidine rings of all 4 compounds At. coordinates are given. In the experiment, the researchers used many compounds, for example, 6-Amino-3-methyl-2-(methylthio)pyrimidin-4(3H)-one (cas: 54030-56-7COA of Formula: C6H9N3OS).
6-Amino-3-methyl-2-(methylthio)pyrimidin-4(3H)-one (cas: 54030-56-7) belongs to pyrimidine derivatives. The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. Pyrimidine derivatives also play an important role in drug development, either in concert with other compounds or on their own.COA of Formula: C6H9N3OS
