4-Bromo-2-nitroaniline is primarily used as an intermediate in the synthesis of dyes and pigments. Its structure allows it to contribute to the production of azo dyes, which are widely used in the textile industry for coloring fabrics. The compound is also utilized in the manufacture of organic chemicals, including pharmaceuticals and agrochemicals, where it serves as a building block for more complex molecules. Additionally, it finds application in research laboratories for the development of new chemical compounds and materials. Its role in these processes is crucial due to its ability to introduce both bromine and nitro functional groups into target molecules, enabling further chemical modifications.
