The title compound, C19H18O5, crystallizes with two independent mol­ecules (A and B) in an asymmetric unit in both of which the two aromatic rings are in a bis­ectional orientation as evidenced by the dihedral angle between them [41.7 (1)° in mol­ecule A and 35.6 (1)° in mol­ecule B]. Both mol­ecules adopt an E configuration with respect to the C=C bond. An intra­molecular C—H...O hydrogen-bond occurs in mol­ecule A. The crystal packing features inter­molecular C—H...O inter­actions.
