In the title compound, C24H26O5, the 2H-chromene ring system is essentially planar, with a maximum deviation of 0.029 (2) Å from the best-fit mean plane incorporating both rings. The dihedral angle between the 2H-chromene ring system and the benzene ring is 21.00 (1)°. In the crystal, pairs of C-HO hydrogen bonds generate an R22(8) ring pattern. These contacts are bolstered by weaker bifurcated C-HO hydrogen bonds.
