Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex organic molecules, particularly in pharmaceuticals and organic materials. Its boronic acid functionality allows for efficient carbon-carbon bond formation under mild conditions. Commonly employed in the development of naphthalene-based compounds with applications in medicinal chemistry, such as anti-inflammatory or anticancer agents. Also utilized in the preparation of fluorescent dyes and optoelectronic materials due to the extended aromatic system. Its ester group enables further functionalization, making it valuable in multi-step synthetic routes.
