2-Hydroxy-N′-[1-(3-methylpyrazin-2-yl)ethylidene]benzohydrazide

The molecule of the title compound, C14H14N4O2, is slightly twisted, with a dihedral angle of 10.06 (14)° between the aromatic rings. An intramolecular N—H⋯O and an intermolecular O—H⋯O hydrogen bond help to establish the crystal structure.
