چکیده
In the title compound, C(12)H(15)N(3)O(5)S, an intra-molecular N-H⋯O hydrogen bond between the hydrazine unit and one of the carbonyl groups may influence the mol-ecular conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds, including one which is bifurcated, link the mol-ecules into a two-dimensional network.
