Used as a chiral building block in the synthesis of pharmaceuticals and fine chemicals. Its enantiomerically pure form makes it valuable in asymmetric synthesis, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry is critical. Commonly employed in the preparation of α-hydroxy esters and other intermediates for drugs involving cardiovascular, central nervous system, and anti-inflammatory agents. Also utilized in the resolution of racemic mixtures and as a starting material in organocatalysis.
