title: 3-Hy-droxy-2-(4-meth-oxy-benzene-sulfonamido)-butanoic acid.
abstract: The title compound, C(11)H(15)NO(6)S, features a distorted tetra-hedral geometry for the S atom. One of the sulfonamide O atoms is approximately coplanar with the benzene ring [C-C-S-O torsion angle = -160.81 (7)°], whereas the other lies well below the plane [C-C-S-O = -29.66 (8)°]. In the crystal, O-H⋯O and C-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the b axis.
