Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) requiring high enantiomeric purity. Its structure supports the creation of complex molecules in central nervous system agents and cardiovascular drugs. Commonly employed in asymmetric synthesis due to its stereochemical stability and reactivity. Also utilized in the preparation of intermediates for antiviral and anti-inflammatory compounds. Preferred in drug design for improving metabolic stability and target selectivity.
