YELLOW TO GREEN-YELLOW FINE POWDER | [Definition]
ChEBI: An anthraquinone that is 9,10-anthraquinone in which the hydrogen at position 2 is substituted by a methyl group. | [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)]
