Abstract: 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) Å. In the crystal, N-H...O and O-H...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 inversion-related molecules [centroid-centroid distance = 3.609 (2) Å].
