In the title compound, C12H8BrClN2O3, the furan ring makes a dihedral angle of 17.2 (2)° with the six-membered ring. An intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation. In the crystal, N-H⋯O hydrogen bonds connect the mol-ecules into chains running along the c-axis direction. The crystal packing is additionally stabilized by C-H⋯O inter-actions into a three-dimensional supramolecular architecture.
在标题化合物C₁₂H₈BrClN₂O₃中，呋喃环与六元环形成17.2 (2)°的二面角。分子内的O—H⋯N氢键稳定了分子构象。在晶体中，N—H⋯O氢键将分子连接成沿c轴方向延伸的链。晶体堆积还通过C—H⋯O相互作用进一步稳定成三维超分子结构。
