Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where stereochemistry plays a critical role in biological activity. Its structure supports the creation of complex molecules in central nervous system agents and cardiovascular drugs. Commonly employed in asymmetric synthesis due to its stable chiral center and ability to direct stereoselective transformations. Also utilized in the preparation of intermediates for medicinal chemistry research and drug discovery programs.
