An orthorhombic polymorph of 2-(1,3-benzothiazol-2-yl)-6-ethoxyphenol.

In the title molecule, C15H13NO2S, an intramolecular O-H...N hydrogen bond forms an S(6) ring motif. The benzothiazole ring system and the benzene ring form a dihedral angle of 8.9 (3) Å. In the crystal, molecules are linked by weak C-H...O hydrogen bonds, forming chains along the b axis. In addition, [pi]-[pi] interactions [centroid-centroid distances = 3.772 (4) and 3.879 (4) Å] are observed
