Used as a chiral building block in asymmetric synthesis, particularly in the preparation of optically active pharmaceuticals and fine chemicals. Its stereochemistry enables selective reactions, making it valuable in the synthesis of complex molecules where control of three-dimensional structure is critical. Commonly employed in catalytic asymmetric transformations and as an intermediate in the development of chiral ligands or catalysts. Also utilized in the resolution of racemic mixtures due to its enantiomeric purity.
