✦ Synopsis

In the molecular structure of the title compound, C~8~H~7~N~5~O~3~S, the thiazole ring is oriented with respect to the barbituric acid ring at a dihedral angle of 5.14 (9)°. In the crystal structure, intermolecular N—H...N and N—H...O hydrogen bonds link the molecules, forming a layer parallel to the ac plane.
