The title compound, C12H15N3O2S, adopts an E configuration with respect to the C=N bond. The propionate group adopts an anti-periplanar (ap) conformation. There are short intra-molecular N-H⋯N and C-H⋯O contacts, forming S(5) and S(6) ring motifs, respectively. In the crystal, mol-ecules are connected into ribbons extending parallel to [010] by pairs of N-H⋯S inter-actions, forming rings with R 2 2(8) graph-set motifs, and by pairs of C-H⋯S inter-actions, where rings with the graph-set motif R 2 1(7) are observed. The O atom of the carbonyl group is disordered over two positions, with a refined occupancy ratio of 0.27 (2):0.73 (2). The studied crystal consisted of two domains.
