Used in pharmaceutical synthesis as a key intermediate for developing bioactive molecules, particularly in the production of centrally acting agents. Its rigid bicyclic structure makes it valuable for designing compounds with high selectivity and potency, especially in neurological and psychiatric drug research. Commonly employed in the development of receptor modulators due to its ability to mimic constrained amino acid geometries. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies involving nitrogen-containing heterocycles.
