Abstract: 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 - interactions between inversion-related benzene rings [centroid-centroid distance = 3.8846 (9) Å].
