Used as a chiral building block in the synthesis of pharmaceuticals and fine chemicals. Its asymmetric structure makes it valuable in the preparation of optically active compounds, particularly in the development of drugs where stereochemistry influences biological activity. Commonly employed in the production of β-blockers and other cardiovascular medications. Also utilized in the synthesis of agrochemicals and specialty polymers requiring enantiomeric purity. Serves as a resolving agent for racemic mixtures due to its ability to form diastereomeric complexes.
