The title compound, C9H10N2O3S, is effectively planar, adopts an E conformation about the central C-N bond and exists in the thione form. N-H⋯S and C-H⋯O hydrogen bonds link the molecules into ribbons. Layers of ribbons are connected to adjacent layers via C-H⋯O interactions. The crystal is a non-merohedral twin, with the twin law describing a rotation of 180° around the [1̄00] direction.
