In the title compound, C15H21ClN2OS, the central chromophore moiety (C2N2OS) is approximately planar, with a maximum deviation of -0.027 (1) Å, and is oriented at a dihedral angle of 86.7 (1)° with respect to the chlorophenyl ring. An intramolecular N-HO hydrogen bond stabilizes the molecular conformation. In the crystal, molecules associate via N-HS hydrogen bonds, forming inversion dimers with motif R22(8). These dimers are further connected by N-HO hydrogen bonds, forming R22(12) dimers. As a result, hydrogen-bonded chains running along  are formed. C-HS interactions also occur. The terminal two C atoms of the butyl chain are disordered over two positions with an occupancy ratio of 0.54:0.46.
