2-Isopropyl-6-methylpyrimidin-4(3H)-one

The molecular structure of the title compound, C8H12N2O, indicates that 2-isopropyl-6-methylpyrimidin-4-ol (the enol–form) undergoes an enol-to-keto tautomerism during the crystallization process. The pyrimidin-4(3H)-one group is essentially planar, with a maximum deviation of 0.081 (1) Å for the O atom. In the crystal structure, symmetry-related molecules are linked into centrosymmetic dimers via pairs of intermolecular N—H...O hydrogen bonds, generating R22(8) rings. These dimers are stacked along the a axis
