  • Applications

    Cyclohexene, 4-ethoxy-1-methyl-4-(1-methylethyl)- (CAS 54982-76-2) is a hydrophobic, moderately volatile cyclohexene derivative that is typically explored as a synthetic intermediate for building functionalized hydrocarbon frameworks in fragrance/personal‑care and fine‑chemical work, as a scaffold in agrochemical and pharmaceutical discovery owing to its modifiable C=C bond (hydrogenation, epoxidation, conjugate additions), and as a hydrophobic solvent or analytical reference in research; its ethoxy group and sterically bulky substitution are useful for probing steric effects in organo‑ and metal‑catalyzed transformations, while the cyclohexene core enables conversion into additives for coatings, adhesives, and polymers (e.g., surface‑modifying precursors, crosslinkable motifs, or specialized plasticizers), making it a versatile platform for tuning odor profile, compatibility with organic matrices, and evaporation behavior in industrial formulations subject to purity and regulatory constraints.
