The organic molecule of the title hydrate, C15H13BrN2O4·H2O, is roughly planar, with a mean deviation of 0.0939 (2) Å. The dihedral angle between the two aromatic rings is 8.2 (3)°. Intramolecular O—H⋯N and O—H⋯O hydrogen bonds are observed. In the crystal, N—H⋯O(water) and O(water)—H⋯O hydrogen bonds lead to a three-dimensional network.
