Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of biologically active indole derivatives. Its boronic acid functionality enables the formation of carbon-carbon bonds, making it valuable in pharmaceutical research and development, particularly in creating novel compounds with potential antitumor, anti-inflammatory, or CNS-modulating activities. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to the stability and reactivity profile of the indole scaffold.
