The title molecule, C11H14N2O2, adopts a trans configuration with respect to the C=N bond. The dihedral angle between the benzene ring and the hydrazinecarboxylate plane is 7.61 (16)°. In the crystal structure, molecules are linked into centrosymmetric dimers by N-HO hydrogen bonds and the dimers are linked together by C-H interactions.
