Sumario:The heterocyclic ring of the title compound, C(9)H(7)BrO(2), obtained by bromination of 4-chromanone with copper bromide, adopts a half-chair conformation. The supramol­ecular structure is governed by a weak C—H⋯O hydrogen bond. There is also π–π stacking between symmetry-related benzene rings; the centroid–centroid distance is 3.9464 (18), the perpendicular distance between the rings is 3.4703 (11) and the offset is 1.879 Å.
