Used as a key intermediate in the synthesis of fluorescent dyes and organic semiconductors due to its reactive bromomethyl group and extended aromatic structure. The nitrile and bromomethyl functionalities allow for further chemical modifications, making it valuable in constructing complex molecules for optoelectronic materials. It is also employed in the preparation of naphthalene-based polymers and ligands for metal-organic frameworks. Its reactivity supports applications in pharmaceutical research, particularly in building blocks for bioactive compounds.
