Used primarily as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of complex indole derivatives. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in pharmaceutical and agrochemical research. Commonly employed in the development of bioactive molecules, including serotonin receptor modulators and kinase inhibitors. Also utilized in materials science for constructing conjugated organic frameworks with optoelectronic properties. Stable and compatible with a wide range of functional groups, it supports late-stage functionalization in drug discovery.
