The condensation of 2-furoic hydrazide and 4-dimethyl amino-benzaldehyde in ethanol yielded a yellow solid formulated as the title compound, CHNO·HO. The crystal packing is stabilized by inter-molecular O(water)-H⋯O,N(carbohydrazide) and N-H⋯O(water) hydrogen bonds, which form a two-dimensional network along the plane. Additional C-H⋯O inter-actions link the mol-ecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47 (6)°. The carbohydrazide moiety, , the C=N-N-C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75 (9)° between their mean planes.
