Uses of Quinacridone: It is used as a pigment to make high performance paints. And it can also be used in artist's paints, including oils, acrylics, and watercolors. In addition, it can react with 2-iodo-propane to get 5,12-diisopropyl-5,12-dihydro-quino[2,3-b]acridine-7,14-dione. This reaction will need reagent 50percent NaOH, catalyst triethylbenzylammonium chloride and solvents toluene and H2O. The reaction time is 32 hours at reaction temperature of 80 °C. The yield is about 50%.
