N-(4-Methyl-phenyl-sulfon-yl)maleamic acid
Abstract:
In the title compound, C(11)H(11)NO(5)S, the dihedral angle between the benzene ring and the amide group is 76.88 (6)°. In the crystal, N-H⋯O(S) and O-H⋯O hydrogen bonds connect the mol-ecules into hydrogen-bonded layers perpendicular to the a axis.

The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
