| | Acid Mordant Orange 14 Usage And Synthesis |
| Uses | Dyes cloth mordanted with Al orange, with Fe red to violet. As indicator in satd alcohol solution. pH 2.0-4.0, color change from golden orange to flat yellow (in water). pH 5.0-6.5 from yellow to purplish red. | | Uses | 1,2-Dihydroxy-3-nitroanthraquinone (cas# 568-93-4) is useful for the development of allosteric PGAM1 inhibitors that are effective at suppressing the proliferation of pancreatic ductal adenocarcinoma cells. | | Preparation | (a) in the presence of boric acid 1,2-Dihydroxyanthracene-9,10-dionein sulfuric acid in the nitration; (b) 1,2-Dihydroxyanthracene-9,10-dionein glacial acetic acid, toluene, petroleum ether or the nitration of nitrobenzene. | | Purification Methods | Crystallise the dye from AcOH (m 244-245o). It has max at 494nm (H2SO4) and forms Cu salts. [Beilstein 8 H 447, 8 II 491, 8 III 3774, 8 IV 2359.] | | Properties and Applications | red light brown (chromium), red orange (aluminum). Insoluble in water. In concentrated sulfuric acid to orange, dilution after yellow.
