Widely used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions, this compound serves as a key intermediate for constructing carbon-carbon bonds in pharmaceutical and agrochemical development. The boronate ester group enables efficient coupling with aryl or vinyl halides under palladium catalysis, making it valuable for building complex indoline-based structures. Its protected indoline nitrogen ensures stability during reactions and allows for selective deprotection later in multistep syntheses. Commonly employed in the preparation of bioactive molecules, including drug candidates targeting neurological disorders and inflammation.
