Used as an intermediate in the synthesis of fluorescent dyes and optoelectronic materials due to its conjugated aromatic structure and halogen substituents. The hydroxyl and bromo groups allow for further functionalization, making it valuable in creating complex organic molecules for sensors and organic semiconductors. Also employed in the preparation of ligands for metal coordination in catalysis research. Its rigid naphthalene backbone contributes to thermal stability and enhances performance in solid-state applications.
