Used as a high-energy density material in propellants and explosives due to its strained bicyclic structure that releases significant energy upon decomposition. Also explored in pharmaceutical research as a bioisostere for aromatic rings or alkynes, offering improved metabolic stability and solubility in drug candidates. Its rigid geometry makes it valuable in materials science for designing rigid molecular spacers in polymers and frameworks. Additionally, serves as a building block in synthetic organic chemistry for constructing complex strained molecules.
