The two molecules in the asymmetric unit of the title compound, C20H19N3O4·CH4O, are paired via O-H(O,N), N-HO, and C-HO hydrogen bonds. The molecular skeleton of the acetohydrazide molecule is close to planar; the benzene and quinoline mean planes form a dihedral angle of 3.9 (3)°. The crystal packing exhibits weak intermolecular C-HO hydrogen bonds and - interactions, indicated by short distances of 3.668 (3) Å, between the centroids of N-containing six-membered rings from neighbouring acetohydrazide molecules.
