Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients requiring high enantiomeric purity. Commonly employed in the development of central nervous system agents, including antidepressants and decongestants. Its chiral amine structure makes it valuable in asymmetric synthesis and resolution processes. Also utilized in the preparation of catalysts and ligands for enantioselective reactions. Frequently found in research settings for drug discovery and optimization due to its structural compatibility with bioactive molecules.
