  • Applications

    1-Heptacosene (CAS 15306-27-1) is a long-chain alpha-olefin that primarily operates as a reactive monomer and processing intermediate in industry. In polymer synthesis, it can be used as a comonomer or terminally functionalized partner in polyolefin production to tailor crystallinity, density and processability. It can be converted by hydroformylation or oxidation to long-chain aldehydes or acids that serve as fragrance ingredients or intermediates for specialty surfactants, lubricants and esters. It may also function as a nonpolar processing solvent or diluent in coatings, inks and adhesives formulations, subject to local regulations and formulation limits. Additionally, it can serve as a starting material for waxes and other long-chain specialty chemicals.
