Used as a chiral building block in the synthesis of pharmaceuticals and fine chemicals. Its stereochemical purity makes it valuable in producing enantiomerically pure compounds, especially in the development of antibiotics, antivirals, and anti-inflammatory agents. Commonly employed in asymmetric synthesis to introduce hydroxy ester functionality with defined stereochemistry. Also utilized in the preparation of biodegradable polymers and as an intermediate in the manufacture of flavors and fragrances.
