Used as a key intermediate in pharmaceutical synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to construct biaryl compounds. Its indole boronic acid structure enables selective formation of carbon-carbon bonds, making it valuable in the development of drug candidates targeting kinase inhibitors and CNS-active agents. The Boc-protected indole ring enhances stability and solubility during reaction processes, allowing for efficient coupling under mild conditions. Commonly employed in medicinal chemistry for lead optimization in the discovery of bioactive molecules. Additionally, it serves as a starting material in the development of fluorescent compounds or organic materials for certain electronic devices.
