| 2-Chloroanthraquinone Usage And Synthesis |
| Chemical Properties | Pale yellow needle crystal. Insoluble in water, soluble in hot benzene, nitrobenzene, concentrated sulfuric acid. |
| Uses | 2-Chloroanthraquinone is an important dye intermediate that can be used to make alizarin and aminoanthraquinone. This product has been evaluated as a photo-reagent for the analysis of ginsenosides using photoreduction fluorescence (PRF) detection method. |
| Preparation | 2-Chloroanthraquinone is prepared by condensing phthalic anhydride and chlorobenzene into p-chlorobenzoylbenzoic acid, and then cyclizing it with sulfuric acid. |
