  • Applications

    1,3-Dimethyl-3-(4-methylpent-3-en-1-yl)bicyclo[2.2.1]heptan-2-ol (CAS 98205-39-1) is a hydrophobic bicyclic terpene alcohol of primary interest in fragrance work, where it can act as a note contributor and a modifier/fixative for fine fragrances, household cleaners, deodorants, personal care, and fabric care due to its relative heat/alkali robustness and an ability—depending on isomeric profile and purity—to lend woody–resinous, slightly camphoraceous and amber-like nuances; it also serves as a precursor to ester/derivative families to broaden olfactory space, while its bulky norbornanol scaffold makes it useful as an organic synthesis intermediate and asymmetric building block for stereochemical studies, as an analytical/sensory reference standard, and as an additive to tune scent profiles in delivery/encapsulation systems (enhancing substantivity, diffusion, and formulation stability), with deployment subject to appropriate safety assessment and regulatory frameworks (e.g., IFRA/REACH) for the intended use.
