Abstract: In the title compound, C₁₉H₁₆O₃, an intramolecular O-HO=C hydrogen bond is formed between the hydroxy and carbonyl groups on the naphthalene ring system, resulting in an S(6) ring. The angles between the C=O bond vector and the least-squares planes of the naphthalene ring system and the benzene ring are 27.63 (6) and 47.99 (7)°, respectively. The dihedral angle between the latter planes is 61.39 (5)°. In the crystal, two molecules are connected by pairs of intermolecular O-HO=C hydrogen bonds, forming centrosymmetric dimers with an R₂²(4) graph-set motif. The molecular packing features C-H interactions.
