Abstract

In the title compound, C13H15NO3S, the sole classical hydrogen-bond donor is involved in an intramolecular O—H...N hydrogen bond. In the crystal structure, pairs of molecules related by inversion centres are linked by pairs of weak intermolecular C—H...O interactions; these centrosymmetric pairs are, in turn, linked further by weak intermolecular C—H...O interactions, forming two-dimensional sheets oriented parallel to (101).
