title: (2R)-2-(1,3-Dioxoisoindolin-2-yl)-4-(methyl-sulfan-yl)butanoic acid.
abstract: The title compound, C(13)H(13)NO(4)S, the 1,3-dioxoisoindolin-2-yl unit is planar (r.m.s. deviation 0.0192 Å) and is oriented at a dihedral angle of 79.14 (18)° to the carboxyl-ate group. An intra-molecular C-H⋯O hydrogen bond leads to the formation of a planar (r.m.s. deviation 0.0419 Å)R(5) ring motif. In the crystal, mol-ecules are connected through O-H⋯O and C-H⋯O hydrogen bonds with R(2) (2)(9) ring motifs into chains extending along the b axis.
