  • Applications

    Alpha-Camphorene (CAS 532-87-6) is a hydrophobic bicyclic monoterpene with camphoraceous, resinous-pine notes, used primarily as a fragrance ingredient to reinforce fresh coniferous and slightly minty facets in fine fragrances, personal care, and household/cleaning scents; in flavors it may be applied at trace levels where permitted; it also serves as an intermediate to synthesize camphor/borneol and epoxidized or hydroxylated derivatives for odor design; in research it is employed as a GC/MS reference for terpene mixtures, as a model VOC in atmospheric oxidation and aerosol-formation studies, and in chemical-ecology assays on semiochemical signaling, with attention to safe handling, exposure control, and compliance with IFRA/REACH or local regulations.
