Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its boronic acid functionality enables Suzuki-Miyaura cross-coupling reactions, allowing for the formation of carbon-carbon bonds in complex molecule assembly. The piperazine ring with a Boc-protected group facilitates solubility and provides a handle for further modification in drug design. Commonly employed in medicinal chemistry for constructing libraries of compounds targeting oncology and inflammatory diseases.
