● 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%.
