Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly antiviral and neuroactive agents. Its rigid adamantane backbone enhances lipophilicity and metabolic stability, making it valuable in drug design for central nervous system targets. Commonly found in research related to NMDA receptor antagonists and treatments for neurological disorders such as Parkinson’s disease and depression. Also explored for its potential in developing novel antiviral drugs due to the adamantane moiety’s known activity against certain viruses.
