The title Schiff base compound, C15H15N3O4, was prepared from a condensation reaction of 3-ethoxy-4-hydroxybenzaldehyde and 3-nitrophenylhydrazine. The molecule is nearly planar; the dihedral angle between the hydroxybenzene ring and the nitrobenzene ring is 6.57 (7)°. O-HO, O-HN and C-HO hydrogen bonding helps to stabilize the crystal structure.
