In the crystal structure of the title compound, C(9)H(12)N(2)O(3), weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into chains. Further weak C-H⋯O hydrogen bonds together with π-π inter-actions [centroid-centroid distance = 3.672 (4) Å] between neighbouring chains lead to a double-chain structure propagating in [100].
