Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biaryl compounds, particularly in pharmaceutical and agrochemical research. Its brominated naphthalene structure enables selective coupling, making it valuable in constructing complex organic molecules for drug development and materials science. Commonly employed in the preparation of fluorescent dyes and organic semiconductors due to the extended aromatic system. Also utilized in the development of receptor ligands and bioactive molecule scaffolds in medicinal chemistry.
