In the title mol-ecule, C(18)H(13)N(3)O(4), the hy-droxy group is involved in the formation of an intra-molecular O-H⋯N hydrogen bond. The dihedral angle between the planes of the benzene ring and the naphthyl ring system is 9.0 (2)°. In the crystal, mol-ecules are linked through N-H⋯O hydrogen bonds into chains along the c axis.
