Chemical properties

Use

●  Organic synthesis intermediates.

●  Used as dye intermediate

●  1-methylaminoanthraquinone, derived by bromination. Bromine was added to the mixture of 1-methylaminoanthraquinone and pyridine, and the mixture was stirred and heated for 6h. Cool, filter out the solid, wash with hot water to remove pyridine hydrobromide, and dry to obtain 4-bromo-1-methylaminoanthraquinone in a yield of 70-74%.
