  • Applications

    4-Octene, (4E)-, CAS 14850-23-8 is an internal olefin (C8) used primarily as an industrial building block. Typical applications include: (1) as a monomer or comonomer in polyolefin synthesis to tailor material properties; (2) a building block for specialty chemicals such as lubricants and surfactants; (3) a precursor for functionalized derivatives via chemical transformations (e.g., oxidation or hydrogenation); (4) a reactive diluent or solvent in coatings and inks formulations. Applications are subject to local regulations and formulation limits.
