In the asymmetric unit of the title hydrazone compound, C(15)H(10)Br(2)N(2)O(4), there are two independent mol-ecules. In each mol-ecule, the five-membered ring adopts a flattened envelope conformation; the flap atoms are displaced by 0.114 (2) and 0.219 (2) Å from the planes of the other four atoms. In one mol-ecule the dihedral angle between the two benzene rings is 22.8 (2)°, while in the other it is 40.8 (2)°. Each mol-ecule displays an E configuration with respect to the C=N bond. In both mol-ecules, intra-molecular O-H⋯N hydrogen bonds are observed. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming chains along the a axis.
