Abstract: The title molecule, C₁₀H₉NO₅S, is composed of two essentially planar units with a dihedral angle of 89.16 (6)° between them. In the crystal structure, there are weak intermolecular C-HO interactions resulting in dimeric pairs of molecules about inversion centres and chains of molecules extended along the a and c axes, thus stabilizing the structure. In addition, benzothiazole rings lying parallel to each other with centroid-centroid distances of 3.679 (2) and 3.999 (2) Å indicate the existence of - stacking interactions.
