title: 3-Methyl-1,4-dioxo-1,4-dihydro-naphthalen-2-yl 4-amino-benzoate.
abstract: The crystal structure of the title compound, C(18)H(13)NO(4), the oxidized form of the drug aminaftone used in venous disease therapy, is characterized by the presence of ribbons of hydrogen-bonded mol-ecules parallel to the [111] crystallographic direction and by stacking inter-actions between rings [centroid-centroid distance between quinone rings = 3.684 (3) Å and between amino-benzoate rings = 4.157 (3) Å] along the ribbons.
