title: 2-Hy-droxy-N'-methyl-benzohydrazide.
abstract: In the title mol-ecule, C(8)H(10)N(2)O(2), there is an intra-molecular hydrogen bond involving the hy-droxy group and the O atom of the carbonyl group. The dihedral angle between the benzene ring and the amide fragment is 87.16 (10)°. The C-N-N-C torsion angle is 88.87 (18)°. In the crystal, N-H⋯N and N-H⋯O hydrogen bonds connect mol-ecules into chains along [100]. In addition, there is a weak C-H⋯π inter-action.
