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. The ester group can be hydrolyzed to the corresponding carboxylic acid or reduced to yield alcohol derivatives, making it versatile in building molecular frameworks. Commonly employed in the development of dyes, fluorescent probes, and bioactive molecules due to the naphthalene core’s favorable photophysical properties. Also utilized in materials science for designing organic semiconductors and liquid crystals.
