Abstract: The two independent molecules of the title compound, C12H10N2O3S, are approximately planar and one is stacked over the other. One of the two molecules interacts with its symmetry-related neighbors to form a hydrogen-bonded helical chain that runs along the shortest axis of the orthorhombic unit cell. The second independent molecule does not form such a chain; instead, it is merely linked to the other independent molecule by a hydrogen bond.
