In the title compound, C(11)H(16)N(2)O(4), the 2,5-dimeth-oxy-phenyl 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 mol-ecular structure is stabilized by a short intra-molecular N-H⋯O hydrogen bond. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.
