title: 4-(5-Bromo-2-hydroxy-phen-yl)but-3-ene-2-one.
abstract: The molecule of the title compound, C(10)H(9)BrO(2), 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 mol-ecules are linked across a centre of inversion to form a hydrogen-bonded dimer by way of two O-H⋯O links.
