Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting the central nervous system. Its structure allows for the creation of compounds with high selectivity and binding affinity to specific receptors, making it valuable in the design of analgesics and muscle relaxants. It is also employed in the preparation of peptidomimetics, where it helps improve metabolic stability and bioavailability of peptide-based drugs. Additionally, it serves as a building block in medicinal chemistry for optimizing pharmacokinetic properties in drug candidates.
