  • Applications

    Applications of (1Z,3E,7Z)-1,7-dimethyl-4-propan-2-ylcyclodeca-1,3,7-triene (CAS 34323-15-4), a C15H24 sesquiterpene hydrocarbon with defined Z/E geometry, are primarily in research and fragrance/flavor analytics: used as a reference/standard in GC–MS and GC×GC to establish retention indices, calibrate response factors, and validate terpene identification in essential oils; applied as a chemical fingerprint marker to authenticate origin and detect adulteration of sesquiterpene-rich oils; employed as a model substrate in organic chemistry to study geometric isomerization, photoisomerization, selective oxidations, partial hydrogenations, and additions on medium-ring trienes, as well as to develop chemoselective and stereoselective catalysts; converted into epoxide/alcohol/hydroperoxide derivatives for biological activity screening and structure–activity relationship work; used as a standard in sensory science and fragrance R&D to probe how oxidation/isomerization affects odor quality and tenacity; leveraged in plant biology and agrochemical studies as a representative volatile to examine plant–insect interactions, semiochemical signaling, and lab-scale repel/attract potential; and included in education/training to demonstrate Z/E effects on spectra (GC–MS, NMR, UV–Vis) and to practice isomer separations, with any practical deployment subject to safety assessments and local regulations.
