Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions, this compound enables the formation of carbon-carbon bonds in the synthesis of complex indole derivatives. It is especially valuable in pharmaceutical and agrochemical research for constructing substituted indole scaffolds, which are common structural motifs in bioactive molecules. Its boronate ester group allows for mild, selective coupling with aryl or heteroaryl halides, making it ideal for late-stage functionalization in drug discovery. Additionally, it supports the development of fluorescent probes and organic electronic materials due to the tunable properties of the indole core.
