Used as a specialty intermediate in organic synthesis, particularly in the development of complex spirocyclic compounds. Its strained ring system makes it valuable for ring-opening reactions and cycloadditions, enabling the construction of polycyclic frameworks found in certain pharmaceuticals and bioactive molecules. It is also employed in polymer chemistry to introduce rigid, oxygen-containing structures that can enhance thermal and mechanical properties of resulting materials. Due to its unique bridged and spiro architecture, it serves as a building block in the synthesis of novel monomers and cross-linking agents.
