Used primarily as an intermediate in organic synthesis, particularly in the production of pharmaceuticals and fine chemicals. Its rigid polycyclic structure makes it valuable in the development of specialty polymers and resins, where it contributes to thermal stability and mechanical strength. It also finds use in the synthesis of ligands for catalysis and in the preparation of novel organic frameworks for research applications. Due to its reactivity, it is employed in Friedel-Crafts acylation and other electrophilic reactions to build complex molecular architectures.
