Used as an intermediate in the synthesis of dyes and pigments, particularly for producing azo dyes that exhibit good light and thermal stability. It also serves in the preparation of pharmaceuticals, where its aromatic amine functionality allows for coupling reactions to build bioactive molecules. Additionally, it finds use in the development of organic semiconductors and fluorescent probes due to its extended aromatic structure and ability to undergo functionalization. Its bromine substituent enables cross-coupling reactions, making it valuable in materials science and medicinal chemistry research.
