6-Bromo-2,4-dinitroaniline

Blues are the single most important color in the disperse class, both in terms of amounts produced and doUar sales volume. Among all dyes. Disperse Blue 79 (100) (6-bromo-2,4-dinitroaniline [1817-73-8] coupled to 3-bis-(2-acetoxyethyl)-amino-/)-acetophenetidine [20249-05-2]) was the highest volume dye in the late 1980s and continues. As reported in 1985, the United States produced 2872 tons valued at 7.7 million. 

Odier bromine-containing dye intemiediates include 6-bromo-2,4-dinitroaniline [1817-73-8] C H BrN O, and 5,7-dibromoisatin [6374-91-0] CgH2Bi2N02. Bromodinitroaniline is used in making a2o dyes and dibromoisatin is used in making Alizarin Indigos B, 3R, and G.
