Used as an intermediate in organic synthesis, particularly in the preparation of naphthalene-based compounds for pharmaceuticals and agrochemicals. Its bromine functionality allows for cross-coupling reactions, such as Suzuki or Heck reactions, enabling the construction of complex aromatic systems. Also employed in the development of fluorescent dyes and optoelectronic materials due to the naphthalene core’s photophysical properties. The ester group can be hydrolyzed or transformed into other functional groups, increasing its utility in multi-step syntheses.
