Abstract: In the title mol­ecule, C9H9NO2, the non-H atoms are essentially coplanar with a maximum deviation of 0.027 (2) Å for the C atom of one of the methyl groups. In the crystal, the mol­ecules are arranged into centrosymmetric pairs via pairs of C-H...O and C-H...N inter­actions whereas [pi]-[pi] stacking inter­actions between the benzene rings [centroid-centroid distance 3.91001 (15) Å] organize them into polymeric strands propagating along the a-axis direction. There is a step of 0.644 (2) Å between the two planar parts of the centrosymmetric pair. In neighboring strands related by the n-glide operation, the aromatic rings are tilted by 29.08 (2)°.
