Used primarily in pharmaceutical research as a key intermediate in the synthesis of bioactive compounds, particularly those targeting neurological pathways. Its rigid bicyclic structure and functional groups make it valuable in the development of receptor ligands, especially for nicotinic acetylcholine receptors. It is also employed in the design of novel therapeutic agents for cognitive disorders, including Alzheimer's and schizophrenia, due to its ability to mimic structural motifs found in natural neurotransmitters. Additionally, it serves as a scaffold in medicinal chemistry for optimizing drug selectivity and metabolic stability.
