Used as a chiral building block in pharmaceutical synthesis, particularly in the development of central nervous system agents. Its structure supports the creation of bioactive molecules due to the presence of both amine and hydroxyl functional groups in a stereochemically defined arrangement. Commonly employed in the production of analgesics, antipsychotics, and nicotinic receptor modulators. Also utilized in the synthesis of natural product analogs and investigational drugs where stereochemistry plays a critical role in biological activity.
