Used as a key chiral intermediate in the synthesis of pharmaceutical agents, particularly in the development of selective enzyme inhibitors and central nervous system therapeutics. Its stereochemistry enables high enantioselectivity in drug formulations, improving potency and reducing off-target effects. Commonly employed in the production of antiviral and neurodegenerative disease treatments due to its ability to cross the blood-brain barrier efficiently. Also utilized in asymmetric synthesis routes where amine functionality acts as a directing group or catalytic site.
