Used as a key intermediate in the synthesis of antiviral and antiparkinsonian drugs. It plays an important role in the preparation of adamantane-based derivatives, particularly in the development of compounds with activity against influenza A virus. Its rigid structure enhances the stability and bioavailability of active pharmaceutical ingredients. Commonly employed in medicinal chemistry for structure-activity relationship studies involving neuroactive agents. Also utilized in the production of specialty polymers and as a building block in organic synthesis where steric hindrance and lipophilicity are advantageous.
