Used as a chiral intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its hydroxyl and ester functional groups allow for further chemical modifications, making it valuable in constructing complex molecules. Commonly employed in asymmetric synthesis routes for central nervous system agents and cardiovascular drugs. Also utilized in research settings for developing enantioselective catalysts and studying reaction mechanisms involving chiral building blocks.
