The asymmetric unit of the title compound, C(14)H(11)BrN(2)O(3), contains two crystallographically independent mol-ecules with slightly different conformations with respect to the aromatic rings; the dihedral angles between the two benzene rings in the two mol-ecules are 55.0 (7) and 16.3 (7)°. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds, forming chains running along the a axis.
标题化合物C(14)H(11)BrN(2)O(3)的不对称单元包含两个晶体学独立的分子，它们相对于芳香环具有略有不同的构象；两个分子中两个苯环之间的二面角分别为55.0 (7)°和16.3 (7)°。在晶体结构中，分子通过分子间的N-H⋯O、O-H⋯O和O-H⋯N氢键相连，形成沿a轴延伸的链。
