title: N'-(3-Ethoxy-2-hydroxybenzylidene)-benzenesulfonohydrazide.
abstract: There are two mol-ecules in the asymmetric unit of the title compound, C(15)H(16)N(2)O(4)S, both of which are stabilized by an intra-molecular O-H⋯N hydrogen bond. Inter-molecular N-H⋯O hydrogen bonds lead to [101] chains of mol-ecules in the crystal structure.
