%X The structure of the title compound, C19H17BrN2O3, consists of two cyclic groups, viz. 4-(methoxycarbonyl)phenyl and 6-(4-bromophenyl)-3-oxo-2,3,4,5-dihydropyridazin-4-yl, which are linked by a methylene spacer. The pyridazine ring is twisted and the dihedral angle between its mean plane and that of the bromophenyl mean plane is 17.2 (2)¡ã. The 4-(methoxycarbonyl)phenyl group shows a quasi-planar conformation, where the dihedral angle between the mean planes of the phenyl ring and carboxylate ester group is 7.9 (4)¡ã. Centrosymmetric intermolecular N¡ªH...O hydrogen bonds form dimers. These are linked by C¡ªBr...O=C interactions [Br...O = 3.10 (1)  ] to form a one-dimensional polymeric structure running along the [1overline{2}0] direction.
