Ethyl 3-oxo-2-[(4-sulfamoylphenyl)hydrazono]butyrate

Abstract

In the title compound, C12H15N3O5S, an intra­molecular N—H⋯O hydrogen bond between the hydrazine unit and one of the carbonyl groups may influence the mol­ecular conformation. In the crystal structure, inter­molecular N—H⋯O hydrogen bonds, including one which is bifurcated, link the mol­ecules into a two-dimensional network.
