Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of neuroactive compounds and central nervous system agents. Its rigid bicyclic structure enhances metabolic stability and influences receptor binding selectivity. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies, especially in optimizing drug candidates targeting ion channels and G-protein-coupled receptors. Also utilized in the preparation of fluorinated analogs to improve bioavailability and membrane permeability.
