Used as an intermediate in organic synthesis, particularly in the preparation of naphthalene-based pharmaceuticals and agrochemicals. Its bromoalkyl functional group allows for easy alkylation and ring closure reactions, making it valuable in constructing fused polycyclic compounds. Commonly employed in the development of fluorescent dyes and optoelectronic materials due to the naphthalene core’s strong luminescent properties. Also utilized in the synthesis of ligands for metal-catalyzed reactions and in the production of specialty polymers with enhanced thermal stability.
