  • Applications

    In fine-chemical research and manufacturing, 12-Oxabicyclo[9.1.0]dodeca-4,7-diene, 1,5,9,9-tetramethyl- (CAS 74282-07-8) is considered a strained terpenoid-like scaffold bearing two double bonds and a ring oxygen, enabling its use as an intermediate for oxidative, hydrogenative, ring-opening, or rearrangement pathways (e.g., epoxidation/hydroboration–oxidation, ozonolysis, Diels–Alder chemistry, and ring-opening metathesis/cationic initiation for suitable derivatives) to access lactones, diols, epoxides, specialty polymers, and asymmetric building blocks; in flavor and fragrance technology, selected derivatives are screened for woody–herbal–citrus notes and potential fixative behavior in hydrophobic matrices, while in analytics it can serve as a reference or process-control standard to assess GC resolution and volatility of oxygenated cyclic hydrocarbons; its rigid, hydrophobic framework also makes the compound/its derivatives useful as a viscosity modifier in water-repellent coating formulations or as a model substrate to probe kinetics, stereoselectivity, and steric effects in organic reactions; for any application, suitability, safety, and regulatory compliance must be verified.
