3-(2-Chloro-3-hy­droxy-4-meth­oxy­phen­yl)-1-(4,5-dimeth­oxy-2-methyl­phen­yl)prop-2-en-1-one

The title compound, C₁₉H₁₉ClO₅, is a chloro derivative of a biologically significant chalcone family. The mean plane of the two substituted benzene rings are twisted by 55.33 (8)° with respect to each other. An intra­molecular C—H...Cl hydrogen bond generates an S(5) graph-set motif. In the crystal, a bifurcated O—H...(O,O) hydrogen bond leads to an R₁²(5) graph-set motif and to the formation of zigzag chains propagating along the c-axis direction. A weak π–π inter­action involving the methyl­phenyl rings [centroid–centroid distance = 3.8185 (10) Å] and C—H...π inter­actions also occur.
