The title hydrazone compound, C15H13N3O3·CH3OH, crystallized as a methanol solvate. The hydrazone mol­ecule has an E configuration about the C=N bond and is almost planar, with a dihedral angle between the benzene rings of 5.3 (3)°. In the crystal, the hydrazone mol­ecules are linked via the methanol solvent mol­ecule through N—H⋯O and O—H⋯O hydrogen bonds, so forming chains propagating along the a-axis direction.
