| 2-Methyl anthraquinone Usage And Synthesis |
| Chemical Properties | YELLOW TO GREEN-YELLOW FINE POWDER | | Uses | 2-Methylanthraquinone is used as a pharmaceutical intermediate. It is used in smog dyes.2-Methylanthraquinone may be used in the preparation of potential bioreducible anthraquinone derivatives. | | Uses | 2-Methylanthraquinone may be used in the preparation of potential bioreducible anthraquinone derivatives. | | Definition | ChEBI: 2-methylanthraquinone is an anthraquinone that is 9,10-anthraquinone in which the hydrogen at position 2 is substituted by a methyl group. It derives from a 9,10-anthraquinone. | | Reactions | The compound is produced by the reaction of phthalic anhydride and toluene. It can be chlorinated to give 1-chloro-2-methylanthraquinone. Nitration gives 1-nitro-2-methylanthraquinone, which can be reduced to 1-amino-2-methyl derivative. Oxidation of the methyl group gives anthraquinone-2-carboxylic acid. | | Synthesis Reference(s) | Canadian Journal of Chemistry, 44, p. 2881, 1966 DOI: 10.1139/v66-428 | | Synthesis Reference(s) | Organic Syntheses, Coll.
