Abstract: In the title compound, C12H15NO5, the dihedral angle between the benzene ring and the C atoms of the terminal isopropyl group is 83.48 (16)°. Intramolecular N-HO and O-HO hydrogen bonds generate S(5) and S(6) rings, respectively. In the crystal, molecules are linked by O-HO hydrogen bonds, generating C(7) chains propagating in . Weak aromatic - stacking [centroid-centroid separation = 3.604 (3) Å] is also observed.
