The Schiff base of the title compound, C15H14N4O6·C3H7NO, was obtained from the condensation reaction of 3-ethoxy-2-hydroxybenzaldehyde and 2,4-dinitrophenylhydrazine. The dihedral angle between the benzene rings is 3.05 (10)° and intramolecular N-H...O and O-H...O hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal, the Schiff base and dimethylformamide solvent molecules are linked by an O-H...O hydrogen bond.
