The title compound, C(12)H(17)NO(3), adopts a folded conformation with a C-C(NH(2))-C(=O)-O torsion angle of -95.9 (2)°. In the crystal, mol-ecules are linked by an O-H⋯N hydrogen bond, forming helical chains along the b-axis direction. Weak N-H⋯O and C-H⋯O hydrogen bonds are observed between the chains.
