Used in organic synthesis as a key intermediate for Suzuki-Miyaura cross-coupling reactions, enabling the formation of biaryl and aryl-heteroaryl bonds in pharmaceutical development. Its boronate ester group facilitates efficient coupling with aryl halides under palladium catalysis, making it valuable in constructing complex molecules for drug discovery. Particularly useful in synthesizing kinase inhibitors and other bioactive compounds where fluorinated indolinone scaffolds enhance metabolic stability and binding affinity.
