In the molecule of the title compound, C16H14O5, all non-H atoms are approximately co-planar [maximum atomic deviation = 0.064 (5) Å]. The hydroxy group is a hydrogen-bond donor to a carbonyl O atom. Weak intermolecular C—H⋯O hydrogen bonding is present in the crystal structure. The crystal structure is ’whole-molecule disordered’ about an axis that runs approximately along the length of the molecule; the occupancy of the two disorder components was set as exactly 0.5. An intramolecular O—-H⋯O hydrogen bond exists in each component.
