The title molecule, C12H14N2O4, adopts a trans configuration with respect to the C=N double bond. The amino group is involved in an intramolecular N—H...O hydrogen bond. In the crystal structure, intermolecular O—H...O hydrogen bonds link the molecules into doubled sheets parallel to the (101) plane.
