چکیده
The six-membered ring of the title compound, C(8)H(11)NO(3), adopts an envelope shape with the C atom in the meta position of the carbonyl representing the flap. This atom is disordered over two positions in an 0.865 (6): 0.135 (6) ratio. In the crystal, a two-dimensional supra-molecular network parallel to the ac plane is built up from O-H⋯O and N-H⋯O hydrogen bonds.
