1-Amino-4-bromonaphthalene is primarily utilized in the synthesis of dyes and pigments due to its naphthalene backbone, which is effective in creating colorfast and stable compounds. It serves as an intermediate in the production of organic compounds, particularly in the development of fluorescent dyes used in biological staining and imaging. Additionally, it is employed in research settings for studying organic reactions and mechanisms, especially those involving halogenated aromatic amines. Its structure also makes it a candidate for use in the preparation of pharmaceuticals and agrochemicals, where it can act as a building block for more complex molecules.
