Used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system agents. Its enantiomeric purity makes it valuable for creating active ingredients in antidepressants and antipsychotic drugs. The compound's amine functionality allows for easy derivatization, enabling its incorporation into more complex molecules. It is also employed in asymmetric synthesis and as a resolving agent for racemic mixtures. Due to the presence of the methylthio group, it can participate in further functional group transformations, expanding its utility in medicinal chemistry and drug discovery processes.
