Used in pharmaceutical synthesis as an intermediate for developing biologically active compounds, particularly in the creation of receptor agonists and antagonists. Commonly employed in the development of central nervous system (CNS) agents due to its structural compatibility with neurotransmitter receptors. Also utilized in the preparation of kinase inhibitors and other enzyme modulators in medicinal chemistry research. Its amine and pyrrolidine functional groups allow for easy derivatization, making it valuable in library synthesis for drug discovery.
