Abstract: The title compound, C₁₁H₁₂O₃, is essentially planar, with an r.m.s. deviation of 0.179 Å from the mean plane through the 14 non-H atoms in the molecule. The benzene ring and the pyranone mean plane are inclined at 13.12 (6)° to one another and the pyranone ring adopts a flattened chair conformation. In the crystal, O-HO hydrogen bonds and C-HO contacts form R₁²(6) rings and link molecules into chains along b. Additional C-HO contacts generate inversion dimers, with R₂²(8) ring motifs, and form sheets parallel to (-102) which are linked by C-H interactions.
