The title compound, C 10 H 11 N 3 O 3 , was synthesized by the reaction of 3,5-bis­(ethoxy­carbon­yl)-2-formyl-4-methyl-1 H -pyrrole and hydrazine hydrate. The angle between the pyrrole ring and the pyridazinone ring is 0.93 (9)°. In the crystal, inter­molecular N—H⋯O and N—H⋯N hydrogen-bond inter­actions link the mol­ecules into a two-dimensional network.
