In the crystal structure of the title compound, C11H15N3O2S, molecules are linked by pairs of N-HO and O-HS hydrogen, forming inversion dimers. These dimers are linked by N-HS hydrogen bonds, forming double-stranded chains propagating along the b-axis direction. The two C atoms of the end chain of the molecule are disordered over two sets os sites [occupancy ratio 0.574 (9):0.426 (9)].
