In the title compound, C8H11NO2S, the aldehyde group is approximately coplanar with the thiophene ring [maximum deviation = 0.023 (2) Å]. In the crystal, molecules are linked by O—H
O hydrogen bonds into supramolecular chains propagating along the a-axis direction.

In the cation of the title hydrated salt, C19H21N2O2S2+·I−·H2O, the benzothiazolium ring system is approximately planar [maximum deviation = 0.0251 (15) Å], and it makes a small dihedral angle of 1.16 (18)° with the plane of the thiophene ring. In the crystal, the cations, anions and crystalline water molecules are linked by classical O—HO, O—HI and weak C—HO hydrogn bonds, forming a three-dimensional supramolecular network. π–π stacking is observed between parallel thiazole rings of adjacent cations [centroid–centroid distance = 3.5945 (16) Å].
