In the mol-ecule of the title compound, C(9)H(11)NO(2), the methyl C atom bonded to the ring and the N atom lie in the benzene ring plane. An intra-molecular O-H⋯O hydrogen bond results in the formation of a five-membered planar ring, which is oriented at a dihedral angle of 81.37 (3)° with respect to the benzene ring. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules stacked along the b axis. There are also π-π inter-actions between benzene rings with a face-to-face stacking distance of 3.434 Å.
在标题化合物C₉H₁₁NO₂的分子中，与环相连的甲基碳原子和氮原子位于苯环平面内。分子内的O—H⋯O氢键导致形成一个五元平面环，该环相对于苯环的二面角为81.37（3）°。在晶体结构中，分子间的O—H⋯O氢键连接着沿b轴堆叠的分子。苯环之间还存在π-π相互作用，面对面堆叠距离为3.434 Å。
