Used primarily as a building block in organic synthesis, especially in pharmaceuticals and agrochemicals. Its rigid adamantane structure enhances lipophilicity and metabolic stability in drug molecules, making it valuable in designing bioactive compounds. Commonly employed to introduce the adamantyl group into larger molecules through acylation reactions. Applied in the development of antiviral, anti-inflammatory, and central nervous system agents. Also utilized in polymer chemistry to modify material properties such as thermal stability and rigidity.
