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. Its structure supports the creation of compounds with neurological activity, including antidepressants and antipsychotics. The amine functionality allows for easy derivatization, making it valuable in medicinal chemistry for building complex molecules. It is also employed in the preparation of pyrrolidine-based catalysts and chiral ligands used in asymmetric synthesis.
