In the title compound, C(10)H(11)NO(4)·H(2)O, the carboxyl group is twisted at a dihedral angle of 6.1 (3)° with respect to the benzene ring. In the crystal, the organic mol-ecules are linked by pairs of O-H⋯O hydrogen bonds involving both carboxyl groups, forming zigzag chains propagating along the b-axis direction. The water mol-ecules form [100] chains linked by O-H⋯O hydrogen bonds. The organic mol-ecule and water chains are cross-linked by N-H⋯O(water) and O(water)-H⋯O hydrogen bonds, generating (001) sheets.
在标题化合物C₁₀H₁₁NO₄·H₂O中，羧基相对于苯环扭转的二面角为6.1 (3)°。在晶体中，有机分子通过涉及两个羧基的O—H⋯O氢键对相连，形成沿b轴方向延伸的锯齿链。水分子通过O—H⋯O氢键形成[100]链。有机分子链和水分子链通过N—H⋯O(水)和O(水)—H⋯O氢键交联，形成(001)层。
