In the title compound, C(17)H(20)N(2)O(4), the 2,5-dimeth-oxy-phenyl unit is almost planar, with an r.m.s. deviation of 0.015 Å. The dihedral angle between the 2,5-dimeth-oxy-phenyl ring and the urea plane is 20.95 (8)°. The H atoms of the urea NH groups are positioned syn to each other. 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.
