title: N,N-Bis(2-hy-droxy-eth-yl)-4-methyl-benzene-sulfonamide.
abstract: In the title compound C(11)H(17)NO(4)S, an intra-molecular O-H⋯O hydrogen bond forms an S(8) ring and determines the conformation of the bis-(2-hy-droxy-eth-yl) segment of the mol-ecule, holding the two CH(2)CH(2)OH groups close to coplanar (r.m.s. deviation = 0.185 Å). In the crystal, O-H⋯O hydrogen bonds link the mol-ecules into zigzag chains along the b axis. Weaker additional C-H⋯O and C-H⋯π contacts generate a three dimensional network, with mol-ecules stacked along the b-axis direction.
