Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its rigid adamantane-like structure enhances metabolic stability and bioavailability in drug candidates. Commonly employed in the preparation of antiviral and neuroprotective agents. Also utilized in the design of prodrugs due to the hydroxyl group, which allows for esterification or conjugation. Shows potential in medicinal chemistry for improving blood-brain barrier penetration.
