In the title compound, C(13)H(17)N(2)OS(+)·Cl(-), the thia-zolium ring mean plane makes a dihedral angle of 55.46 (9)° with the benzene ring. In the propanol group, the N-C-C-C and N-C-C-O torsion angles are 172.58 (15) and 52.9 (2)°, respectively, and the S-C-C-C torsion angle is 178.99 (18)°. In the crystal, mol-ecules are linked by O-H⋯Cl and N-H⋯Cl hydrogen bonds, forming zigzag chains along [001]. There is also a C-H⋯Cl inter-action present.
