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, π–π inter­actions [centroid–centroid distances = 3.772 (4) and 3.879 (4) Å] are observed.
