This compound is primarily utilized in the field of organic synthesis, where it serves as a chiral building block for the creation of complex molecules. Its structure, featuring both an amino group and a phenylthio group, makes it valuable in the development of pharmaceuticals, particularly in the synthesis of enantiomerically pure drugs. It is often employed in peptide chemistry to introduce specific functional groups or to modify peptide chains, enhancing their biological activity or stability. Additionally, it finds application in asymmetric synthesis, aiding in the production of compounds with high stereochemical purity, which is crucial in the development of active pharmaceutical ingredients (APIs) and fine chemicals.
