Used as an intermediate in pharmaceutical synthesis, particularly in the production of active pharmaceutical ingredients (APIs) that require piperazine moieties. Its hydroxyl and protected amine functional groups allow for selective chemical modifications, making it valuable in drug development for introducing solubility or polarity enhancements. Commonly employed in the synthesis of kinase inhibitors, antiviral agents, and central nervous system (CNS) drugs. Also utilized in the preparation of functionalized polymers and as a building block in combinatorial chemistry for high-throughput screening libraries.
