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—HO and O—HO hydrogen bonds link the molecules into chains running along the b-axis direction. The chains also feature π–π interactions between pyridine and benzene rings of inversion-related molecules [centroid–centroid distance = 3.609 (2) Å].

In the title hydrate, C12H13NO4·H2O, the piperidine ring that is fused to the benzene ring is in a sofa conformation with the chiral C atom lying 0.4084 (18) Å out of the plane of the nine fused-ring atoms. In the crystal, O—HO and N—HO hydrogen bonds link the organic molecules and water molecules into chains running along the b-axis direction. The chains are further connected into layers parallel to the bc plane by π–π interactions between inversion-related benzene rings [centroid–centroid distance = 3.8846 (9) Å].
