Abstract: In the title molecule, C12H12N4O3S, there is an intramolecular O-H...N hydrogen bond. The dihedral angle between the benzene and triazine rings is 65.9 (3)°. In the crystal, N-H...S and O-H...N hydrogen bonds link the molecules into chains along [010]. In addition, there are weak [pi]-[pi] stacking interactions between symmetry-related triazine rings with a centroid-centroid distance of 3.560 (3)°.
