Used as a key building block in medicinal chemistry, particularly in the design of bioactive molecules and pharmaceuticals. Its rigid bicyclic structure enhances metabolic stability and improves pharmacokinetic properties when incorporated into drug candidates. Commonly employed in the development of CNS-targeted agents and kinase inhibitors due to its favorable polarity and ability to influence blood-brain barrier penetration. Also utilized in fragment-based drug discovery for its three-dimensional architecture, enabling efficient interactions with protein targets.
