Used in organic synthesis as a key intermediate in Suzuki-Miyaura cross-coupling reactions, enabling the formation of carbon-carbon bonds for constructing complex indoline-based structures. Commonly applied in pharmaceutical research and development of bioactive molecules, particularly in the synthesis of drug candidates targeting neurological disorders and cancer. Its boronate ester group facilitates mild and selective coupling with aryl or heteroaryl halides, making it valuable in medicinal chemistry and materials science.
