N-(4-Methylphenylsulfonyl)succinamic acid

Abstract

In the crystal structure of the title compound, C11H13NO5S, the amide C=O and the carboxyl C=O groups of the acid segment orient themselves away from each other. The dihedral angle between the benzene ring and the amide group is 69.0 (2)°. In the crystal, N—H...O and O—H...O hydrogen bonds link the molecules into layers parallel to the bc plane.
