Used in organic synthesis, particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds. It serves as a key building block in the preparation of pharmaceuticals and biologically active compounds. Its boronic acid group enables coupling with aryl or vinyl halides, while the cyclopentyloxy substituent provides steric and electronic properties useful in drug design. Commonly applied in medicinal chemistry for constructing complex aromatic systems and in the development of kinase inhibitors and other therapeutic agents.
