Abstract
The title compound, C15H12F2O3, has been obtained by the reaction of 2,4-dihydroxylacetonephenone, potassium carbonate and 3,5-difluorobenzyl bromide. The hydroxy group is involved in an intramolecular O—H⋯O hydrogen bond in each of the two independent molecules in the asymmetric unit. The dihedral angle between the aromatic rings is 0.5 (2)° in one molecule and 1.9 (2)° in the other. In the crystal, weak C—H⋯O interactions link the molecules into tetrameric units aligned perpendicular to b.
