Widely used as a chiral building block in the synthesis of pharmaceuticals, particularly in the development of central nervous system (CNS) drugs. It serves as a key intermediate in the production of compounds targeting neurotransmitter systems, such as dopamine and serotonin receptors. Its enantiomeric purity is crucial for ensuring the desired pharmacological activity and minimizing side effects in therapeutic agents. Additionally, it finds application in research settings for studying receptor binding and drug-receptor interactions, aiding in the design of more effective and selective medications.
