title: (2R)-2-(1,3-Dioxoisoindolin-2-yl)-3-methyl-butanoic acid.
abstract: In the title compound, C(13)H(13)NO(4), the dihedral angle between the nine-membered phthalimino ring system and the carb-oxy-lic acid group is 67.15 (9)°. An intra-molecular C-H⋯O close contact, which forms an S(6) ring, may help to establish the mol-ecular conformation. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, thereby forming C(7) chains propagating in [010].
