Used primarily as a building block in organic synthesis, especially in the development of pharmaceuticals. Its rigid bicyclic structure makes it valuable for designing bioactive molecules, including neuroactive compounds and receptor ligands. Commonly employed in the synthesis of nicotinic acetylcholine receptor modulators due to structural similarity to nicotine. Also utilized in the preparation of catalysts and chiral auxiliaries for asymmetric synthesis. Its hydrochloride salt form enhances stability and solubility, facilitating use in aqueous and polar environments.
