In the title compound, C10H13N3O, the hydrazinecarboxamide N—N—C(=O)—N unit is nearly planar [maximum deviation = 0.018 (2) Å] and is inclined at a dihedral angle of 8.45 (10)° with respect to the plane of the phenyl ring. The molecular structure is stabilized by an intramolecular C—HO hydrogen bond which generates an S(6) ring motif. In the crystal, molecules are linked into an inversion dimer by pairs of N—HO and C—HO hydrogen bonds.
