Abstract: The crystal structure of the title compound, C₁₈H₁₃NO₄, the oxidized form of the drug aminaftone used in venous disease therapy, is characterized by the presence of ribbons of hydrogen-bonded molecules parallel to the [111] crystallographic direction and by stacking interactions between rings [centroid-centroid distance between quinone rings = 3.684 (3) Å and between aminobenzoate rings = 4.157 (3) Å] along the ribbons.
