Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of centrally acting agents. Its rigid bicyclic structure with a nitrogen heteroatom makes it valuable in medicinal chemistry for designing compounds that target neurological receptors. It is often incorporated into molecules aiming for enhanced selectivity and binding affinity, especially in serotonergic and dopaminergic systems. The hydrochloride salt form improves stability and solubility, facilitating its use in multi-step organic syntheses. It also finds use in the preparation of chiral building blocks for asymmetric synthesis.
