Used as an intermediate in the synthesis of organic semiconductors and optoelectronic materials. It serves in the preparation of naphthalene-based dyes and fluorescent probes due to its ability to undergo selective substitution reactions. Also employed in the development of liquid crystals and pharmaceuticals where halogenated aromatic frameworks are required. Its reactivity allows for palladium-catalyzed coupling reactions, making it valuable in building complex molecular architectures for research and industrial applications.
