Used as a key intermediate in Suzuki-Miyaura cross-coupling reactions for the synthesis of pharmaceuticals and biologically active compounds. Its boronate ester group enables efficient carbon-carbon bond formation, making it valuable in drug discovery and development. Commonly applied in the preparation of pyrrolidone-containing molecules, which are found in several therapeutic agents targeting neurological disorders and inflammation. Also utilized in materials science for constructing conjugated organic frameworks in optoelectronic devices.
