Abstract: The title compound, C11H12O3, is potentially a butane-2,3-dione derivative but exists in the enol form in the solid state. In the molecule, the 3-hydroxybut-3-en-2-one, benzene and methoxyl fragments are almost co-planar. The 3-hydroxybut-3-en-2-one fragment is almost planar with an r.m.s. deviation of 0.040 Å. The dihedral angle between this plane and that of the benzene ring is 5.88 (4)°. The 4-methoxy group also lies close to the benzene ring plane, with deviations of 0.0206 (11) Å for the O and 0.087 (2) Å for methyl C atoms. Hence, the whole molecule is almost planar with an r.m.s. deviation of 0.0617 Å from a plane through all 14 non-H atoms. In the crystal, the molecules are linked by O-HO hydrogen bonds, generating  chains.
