In the crystal structure of title compound, C9H10N2OS, there are two symmetry-independent mol­ecules, each having an intra­molecular N—H⋯O hydrogen bond generating an S(6) ring motif. The benzene rings and the virtually planar acetyl­thoiurea fragments [r.m.s. deviations = 0.0045 and 0.0341 Å] are oriented at dihedral angles of 50.71 (6) and 62.79 (6)° in the two mol­ecules. In the crystal, N—H⋯S and N—H⋯O hydrogen bonds link mol­ecules via cyclic R22(8) and R22(12) motifs into a one-dimensional polymeric network extending along [101]. The intra- and inter­molecular N—H⋯O inter­actions are part of a three-center hydrogen bond. A C—H⋯S inter­action also occurs.
