Abstract: The title compound, C₈H₉NO₄S, is of interest as a precursor to biologically active sulfur-containing heterocyclic cmpounds. The crystal structure displays the classical O-HO intermolecular hydrogen bonding typical for carboxylic acids forming dimers. Symmetry-related dimers are, in turn, linked through head-to-tail pairs of intermolecular N-HO interactions, giving rise to a zigzag chain along the c axis.
