  • Applications

    2,6-Dimethylocta-2,7-dien-4-ol (CAS 103982-47-4) is an unsaturated allylic alcohol of the monoterpenoid type used in research as a versatile synthetic building block; its internal and terminal C=C bonds together with the hydroxyl group enable transformations such as epoxidation, selective oxidation to ketone/enone, hydroboration–oxidation, allylic rearrangements, and olefin metathesis, making it useful as an intermediate to terpenoid derivatives, potential fragrance precursors, analytical reference material, mechanistic probes, and as a handle to introduce labels or functions in medicinal chemistry and functional materials; intended for research use only and subject to safety/toxicity and sensory evaluation before any consumer application.
