Abstract: The molecule of the title compound, C₁₀H₉BrO₂, a doubly conjugated unsaturated ketone, is almost planar (r.m.s. deviation of the non-H atoms = 0.039 Å). In the crystal structure, two molecules are linked across a centre of inversion to form a hydrogen-bonded dimer by way of two O-HO links.
