Abstract
In the title compound, C11H16N2O4, the 2,5-dimethoxyphenyl moiety is almost planar, with an r.m.s. deviation of 0.026 Å. The dihedral angle between the benzene ring and the plane of the urea moiety is 13.86 (5)°. The molecular structure is stabilized by a short intramolecular N—H⋯O hydrogen bond. In the crystal, intermolecular N—H⋯O and O—H⋯O hydrogen bonds link the molecules into a three-dimensional network.
