title: 2-Hydr-oxy-N'-[1-(3-methyl-pyrazin-2-yl)ethyl-idene]benzohydrazide.
abstract: The mol-ecule of the title compound, C(14)H(14)N(4)O(2), is slightly twisted, with a dihedral angle of 10.06 (14)° between the aromatic rings. An intra-molecular N-H⋯O and an inter-molecular O-H⋯O hydrogen bond help to establish the crystal structure.
