Used as a specialty intermediate in pharmaceutical synthesis, particularly in the development of bioactive molecules and drug candidates. Its rigid bicyclic structure and nitrogen functionality make it valuable for constructing novel heterocyclic compounds. Commonly employed in medicinal chemistry for scaffold diversification and as a building block in the design of enzyme inhibitors or receptor modulators. The trifluoroacetic acid salts enhance solubility and stability during synthetic processes, facilitating coupling reactions and purification steps.
