Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for central nervous system (CNS) drugs and antipsychotic medications. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building complex molecules. Commonly employed in the preparation of receptor agonists and antagonists due to its ability to interact with biological targets through hydrogen bonding and ionic interactions. Also utilized in the creation of novel compounds for research in neuropharmacology and drug discovery.
