In the title mol-ecule, C(8)H(7)NO(2), all the non-H atoms lie essentially in the same plane (r.m.s. deviation = 0.019 Å) In the crystal structure, weak inter-molecular C-H⋯O inter-actions link mol-ecules into chains along [100]. In addition, there are π-π stacking inter-actions between mol-ecules related by the c-glide plane, with alternating centroid-centroid distances of 3.434 (2) and 3.639 (2) Å.
