摘要：
In the title compound, C12H13NO3, the quinoline ring system is approximately planar with a maximum deviation from the least-squares plane of 0.058 (2) angstrom. In the crystal, N-H center dot center dot center dot O and O-H center dot center dot center dot O hydrogen bonds link the molecules into chains running along the b-axis direction. The chains also feature pi-pi interactions between pyridine and benzene rings of inversionrelated molecules [ centroid-centroid distance = 3.609 (2) angstrom].
