Used in organic synthesis as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the formation of biaryl compounds with pharmaceutical relevance. Its boronic acid group facilitates carbon-carbon bond formation under mild conditions, making it valuable in drug discovery and development of functional materials. Commonly employed in the preparation of indole-based bioactive molecules, including potential anti-inflammatory and anticancer agents. Also applied in the synthesis of fluorescent probes and optoelectronic materials due to the extended conjugation achievable through coupling.
