چکیده
In the title mol-ecule, C(15)H(10)BrNO(4)S, the heterocyclic thia-zine ring adopts a half-chair conformation, with the S and N atoms displaced by 0.554 (7) and 0.198 (8) Å, respectively, on opposite sides of the mean plane formed by the remaining ring atoms. The mol-ecular structure is consolidated by intra-molecular O-H⋯O inter-actions and the crystal packing features N-H⋯O and C-H⋯O hydrogen bonds.
