Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents and analgesics. Its structure supports the creation of bioactive molecules due to the presence of both amine and alcohol functional groups in a stereoselective configuration. Commonly employed in the preparation of drug candidates targeting neurological disorders, including antidepressants and antipsychotics. Also utilized in the design of enzyme inhibitors and receptor modulators where stereochemistry plays a critical role in activity.
