In the title compound, C(14)H(13)NO(4)S, a sulfonamide derivative of phenyl glycine, the aromatic rings are inclined at a dihedral angle of 28.03 (12)°. In the crystal, O-H⋯O hydrogen bonds link the molecules into chains propagating in [100] and a weak C-H⋯O interaction cross-links the chains in the c-axis direction. In the previously published polymorph, the dihedral angle between the aromatic rings is 45.52 (18)° and the structure is stabilized by three different types of ring motif.
在标题化合物C₁₄H₁₃NO₄S（一种苯基甘氨酸的磺酰胺衍生物）中，芳环以28.03 (12)°的二面角倾斜。在晶体中，O—H⋯O氢键将分子连接成沿[100]方向延伸的链，并且一个弱的C—H⋯O相互作用在c轴方向上使这些链交联。在先前发表的多晶型物中，芳环之间的二面角为45.52 (18)°，并且结构由三种不同类型的环基序稳定。
