(2-Bromophenyl)(4-hydroxy-1,1-dioxo-2H-1,2-benzothiazin-3-yl)methanone

In the title molecule, C15H10BrNO4S, the heterocyclic thiazine 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 molecular structure is consolidated by intramolecular O—H...O interactions and the crystal packing features N—H...O and C—H...O hydrogen bonds.
