Used as a key intermediate in the synthesis of fluorescent dyes and organic semiconductors due to its naphthalene backbone and reactive ester group. The bromine atom allows for further functionalization via cross-coupling reactions such as Suzuki or Heck couplings, making it valuable in the development of advanced organic materials. Commonly employed in the preparation of naphthalene-based derivatives for use in optoelectronic devices and as building blocks in pharmaceutical research. Its ester functionality enables conversion to carboxylic acids or amides, expanding its utility in medicinal chemistry and material science.
