The title compound, C(11)H(11)N(3)O(2)·H(2)O, was obtained by the reaction of 2-acetyl-phenol with cyano-acetohydrazide in methanol. The asymmetric unit contains two hydrazone mol-ecules and two water mol-ecules of crystallization. There is an intra-molecular O-H⋯N hydrogen bond in each hydrazone mol-ecule.
