Abstract: In the title compound, C19H17BrO3, the ring skeleton is located on a crystallographic mirror plane; two C atoms of the cyclohexene ring are disordered over the two locations to satisfy the preferred ring conformation. In the crystal, C-HO hydrogen bonds link the molecules into chains along the a axis. - stacking interactions between benzoquinone rings, with a centroid-centroid distance of 3.7225 (4) Å, are also observed, which connect the chains into a two-dimensional networkparallel to the ab plane.
