Abstract: The title compound, C10H11N3O3, was synthesized by the reaction of 3,5-bis(ethoxycarbonyl)-2-formyl-4-methyl-1H-pyrrole and hydrazine hydrate. The angle between the pyrrole ring and the pyridazinone ring is 0.93 (9)°. In the crystal, intermolecular N-HO and N-HN hydrogen-bond interactions link the molecules into a two-dimensional network.
