Used as an intermediate in pharmaceutical synthesis, particularly in the development of active pharmaceutical ingredients (APIs) requiring piperazine and amine functional groups. Its protected amine structure makes it valuable in multi-step organic reactions, especially in the preparation of kinase inhibitors, antiviral agents, and central nervous system (CNS) drugs. Commonly employed in medicinal chemistry for building complex molecules due to its stability and selective reactivity. Also utilized in the synthesis of functionalized polymers and ligands for catalysis.
