title: 2-Isopropyl-6-methyl-pyrimidin-4(3H)-one.
abstract: The mol-ecular structure of the title compound, C(8)H(12)N(2)O, indicates that 2-isopropyl-6-methyl-pyrimidin-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 mol-ecules are linked into centrosymmetic dimers via pairs of inter-molecular N-H⋯O hydrogen bonds, generating R(2) (2)(8) rings. These dimers are stacked along the a axis.
