Used in the synthesis of pharmaceuticals, particularly in the development of antiviral and neuroprotective agents. Its rigid adamantane structure enhances lipophilicity and metabolic stability, making it valuable in drug design for improving blood-brain barrier penetration. Also employed as an intermediate in the preparation of ester prodrugs and in the formulation of certain central nervous system medications. Additionally, it finds use in fragrance chemistry due to its stable, long-lasting odor profile.
