Abstract
In the title molecule, C13H16O4, the pyran ring is in a half-chair conformation. There is an intramolecular hydrogen bond involving the ketone O atom and an H atom of a phenol group which forms an S(6) ring. The ketone O atom is also involved in an intermolecular hydrogen bond with a different phenolic H atom of a symmetry-related molecule, forming C(6) chains along the c-axis direction.
