  • Applications

    Reference chemical: Bicyclo[4.1.0]hept-4-ene-3-methanol, 4,7,7-trimethyl- (CAS 15103-32-9). It is commonly used as a chemical intermediate and building block in fragrance chemistry, where the bicyclic aliphatic alcohol scaffold can be converted into aroma compounds and odorants; it may also function as a fragrance ingredient in cosmetics and household products. The hydroxyl group enables derivatization to esters or other derivatives for use in industrial manufacturing, polymers, and coatings. It may be evaluated as a flavor precursor in specialized formulations, subject to local regulations and formulation limits.
