The molecule of the title hydrazine derivative, C15H14N4O6, is essentially planar, the dihedral angle between the substituted benzene rings being 2.25 (9)�. The ethoxy and hydroxy groups are almost coplanar with their bound benzene ring [r.m.s. deviation = 0.0153 (2) A ° for the ten non-H atoms]. Intramolecular N—H� � �O and O—H� � �Oethoxy hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal, molecules are linked by O—H� � �Onitro hydrogen bonds into chains propagating in [010]. Weak aromatic �–� interactions, with centroid–centroid distances of 3.8192 (19) and 4.0491 (19) A ° , are also observed.
