The molecule of the title compound, C16H12O4, is almost planar; the two methoxy groups are slightly out of the plane of the anthraquinone ring system, with C—C—O—C torsion angles of −6.25 (19) and −10.22 (19)°. In the crystal structure, the molecules adopt a herringbone arrangement and form face-to-face slipped antiparallel π–π stacking interactions along the b axis, with an interplanar distance of 3.278 (2) Å.
