Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds in pharmaceutical and agrochemical synthesis. Its indole structure makes it valuable for constructing biologically active molecules, particularly in drug discovery targeting CNS disorders and oncology. The boron-containing group provides high stability and reactivity under mild conditions, improving efficiency in late-stage functionalization of complex molecules. Commonly applied in the development of fluorescent probes due to the indole core’s inherent optical properties, useful in bioimaging and sensor technologies.
