In the title compound, C(15)H(12)N(2)O(5)S, the benzisothiazole group is approximately planar (r.m.s. deviation excluding H atoms and the two O atoms bonded to S = 0.023 angstrom). The dihedral angle between the benzisothiazole ring and the terminal phenol ring is 84.9 (1)degrees. In the crystal, molecules are joined by N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds, and pi-stacking interactions are observed between alternating phenol and benzisothiazole rings [centroid-centroid distances = 3.929 (3) and 3.943 (3) angstrom].
