(E)-3-[4-(Dodec-yloxy)phen-yl]-1-(2-hydroxy-phen-yl)prop-2-en-1-one.

In the title compound, C(27)H(36)O(3), the asymmetric unit consists of two crystallographically independent mol-ecules. The aromatic rings form dihedral angles of 17.1 (2) and 17.6 (2)° in the two molecules. In both mol-ecules, the enone groups adopt an s-cis conformation and the alkoxyl chains are in trans conformations curving out of the zigzag plane. Intra-molecular O-H⋯O hydrogen bonds involving the keto and hydr-oxy groups generate S(6) ring motifs. The mol-ecules are stacked alternately in a head-to-tail fashion along the a axis and the crystal structure is stabilized by weak C-H⋯π inter-actions. The crystal studied was a non-merohedral twin, the ratio of components being 0.788 (2):0.212 (2).
