| Description | 1,4-Diamino-2,3-dihydroanthraquinone (DDA) is a dark purple needle crystal. It is insoluble in water, but soluble in benzene, pyridine, nitrobenzene, and aniline. Can be used to prepare purple smoke bombs. It is highly susceptible to oxidation to 1,4-diaminoanthraquinone (DAA) in the air or during smoke bomb burning. DDA is a weak mutagen in the Salmonella Reversin Assay, and a combustion or oxidation product in the same test, and DAA is a strong mutagen. |
| Dark Greenish Brown Solid | |
| Uses | Leuco-1,4-diaminoanthraquinone (leucamine) is an important precursor for 1,4-diaminoanthraquinone. |
| An anthraquinone-derived dye. A product from the combustion of red and violet smoke mixtures. | |
