In the crystal structure of the title compound, C(11)H(15)NO(4)S, two independent mol-ecules are present per asymmetric unit; they are dimerized through O-H⋯O hydrogen bonds between their carb-oxy groups to generate R(2) (2)(8) loops. An intra-molecular N-H⋯O link in one of the mol-ecules closes an S(5) ring. The dimers are linked by N-H⋯O and C-H⋯O hydrogen bonds to form a three-dimensional network. The C atoms of the isopropyl group of one of the mol-ecules are disordered over two orientations in a 3:1 ratio.
在标题化合物C₁₁H₁₅NO₄S的晶体结构中，每个不对称单元中有两个独立的分子；它们通过羧基之间的O—H⋯O氢键二聚化，形成R₂²(8)环。其中一个分子内的N—H⋯O连接形成一个S(5)环。二聚体通过N—H⋯O和C—H⋯O氢键相连，形成三维网络。其中一个分子异丙基的C原子在两种取向上无序，比例为3:1。
