Used primarily as an intermediate in the synthesis of pharmaceuticals, particularly in the production of antiviral and neuroprotective agents. Its rigid structure enhances metabolic stability and bioavailability in drug molecules. Also employed in the development of advanced polymers and resins, where it contributes to thermal stability and mechanical strength. Additionally, it serves as a building block in the design of novel materials for optoelectronics due to its unique cage-like geometry and electronic properties.
