The title compound, C10H12N2O3, crystallizes with two independent mol­ecules in the asymmetric unit. The side chains in the two independent mol­ecules have slightly different orientations, with the C=N—N—C torsion angle being 169.19 (14)° in one of the mol­ecules and −179.86 (14)° in the other. Each independent mol­ecule adopts a trans configuration with respect to the C=N bond. In the crystal structure, mol­ecules are linked into chains running along [001] by N—H⋯O, N—H⋯N and C—H⋯O hydrogen bonds. In addition, an inter­molecular C—H⋯π inter­action is observed.
