Abstract: The asymmetric unit of the title compound [systematic name: 3-(2,4-dimethoxyphenyl)-1-(4-hydroxyphenyl)propan-1-one], C₁₇H₁₈O₄, contains two independent molecules; these have different conformations with respect to the relative orientation of the aromatic ring planes. The dihedral angles formed by the dimethoxyphenyl and hydroxyphenyl rings in the two molecules are 19.61 (10) and 66.37 (9)°. In the crystal structure, intermolecular O-HO hydrogen-bonding interactions link the molecules into one-dimensional chains running parallel to the c axis.
