In the title compound C11H17NO4S, an intramolecular O—HO hydrogen bond forms an S(8) ring and determines the conformation of the bis(2-hydroxyethyl) segment of the molecule, holding the two CH2CH2OH groups close to coplanar (r.m.s. deviation = 0.185 Å). In the crystal, O—HO hydrogen bonds link the molecules into zigzag chains along the b axis. Weaker additional C—HO and C—Hπ contacts generate a three dimensional network, with molecules stacked along the b-axis direction.
