2-Bromoanthracene is primarily used in organic synthesis as a building block for the preparation of more complex organic compounds. It serves as a key intermediate in the production of dyes, pigments, and fluorescent materials due to its anthracene core, which is known for its luminescent properties. In research, it is employed in studies related to photochemistry and as a precursor in the synthesis of polycyclic aromatic hydrocarbons (PAHs). Additionally, it finds applications in the development of organic semiconductors and optoelectronic devices, where its electronic properties are leveraged. Its bromine atom also makes it a useful reagent in cross-coupling reactions, facilitating the creation of carbon-carbon bonds in various synthetic pathways.
