Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and neuroactive agents. Its rigid adamantane backbone enhances lipophilicity and metabolic stability, making it valuable in drug design for improving bioavailability and blood-brain barrier penetration. Also employed in the development of specialty polymers and resins where thermal stability and structural rigidity are required. Additionally, it serves as a building block in the preparation of advanced organic materials and catalysts due to its unique steric and electronic properties.
