Abstract: In the title compound, C₇H₁₃NO₄, there are two independent molecules in the asymmetric unit. All bond lengths and angles in the molecules are in normal ranges. The ¹ and ² torsion angles are 159.9 (4) and -23.4 (5)°, respectively, in the first molecule, and the ³ and ⁴ torsion angles 157.7 (4) and -26.7 (5)°, respectively, in the second. Each of the independent molecules has a different comformation. The translationally and screw-related molecules are connected by N-HO hydrogen bonds, forming a two-dimensional network parallel to the ac plane.
