  • Applications

    1-Methyl-2-methylenecyclohexane (CAS 2808-75-5) is primarily used as an odor-active intermediate in fragrance and flavor chemistry, serving as a building block to synthesize aroma compounds and to modulate scent profiles in formulations. In cosmetics and personal care, it may appear as a fragrance ingredient in small concentrations, while in household products it is used as a fragrance additive in cleaners and air fresheners. In industrial manufacturing, it can function as a non-polar intermediate or diluent in specialty formulations and as a precursor to aroma-related polymers or resins for coatings and inks. These applications reflect its role as a fragrance/odorant material and synthetic intermediate rather than a primary functional ingredient.
