Abstract: 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-H contacts generate a three dimensional network, with molecules stacked along the b-axis direction.
