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 stimulant medications. Commonly employed in asymmetric synthesis to introduce chirality in drug candidates. Also utilized in the preparation of selective monoamine reuptake inhibitors. Serves as an intermediate in the production of appetite suppressants and ADHD treatments.
