Used in organic synthesis as an intermediate for pharmaceuticals and fine chemicals. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. Commonly employed in the development of dyes, fluorescent probes, and polycyclic compounds due to the naphthalene backbone’s photophysical properties. Also utilized in the preparation of naphthoate ester derivatives for research in material science and medicinal chemistry.
