Used in pharmaceutical synthesis as a chiral building block for developing bioactive molecules, particularly in the production of neuroactive drugs targeting CNS disorders. Its rigid bicyclic structure and functional groups make it valuable for enhancing selectivity and potency in drug candidates. Commonly employed in the development of enzyme inhibitors and receptor modulators due to its ability to mimic natural neurotransmitters. The trifluoroacetate salt form improves solubility and stability during synthetic processes.
