Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of selective serotonin reuptake inhibitors (SSRIs) and other central nervous system agents. Its enantiomerically pure amine functionality allows for precise stereochemical control during drug synthesis. Commonly employed in the preparation of active pharmaceutical ingredients where the (R)-configuration is required for optimal biological activity. Also utilized in research settings for the development of novel therapeutic compounds targeting neurological disorders.
