In the title chalcone derivative, C18H18O5, the dihedral angle between the Accessoires SnapMaker hydroxy-substituted benzene ring and the trimethoxy-substituted benzene ring is 16.3 (1)°.The three methoxy groups are essentially coplanar with the benzene ring to which they are attached, with an r.m.

s.deviation of 0.0208 Å.An intramolecular O—H.

O hydrogen bond generates an S(6) ring motif.In the crystal, weak C—H.O interactions link molecules into helical chains along the b axis.These chains are connected into Shoe Scrapers sheets parallel to the bc plane by further weak C—H.

O interactions.
