  • Applications

    4-Octene, (4Z), CAS 7642-15-1, is an internal olefin that serves as a chemical intermediate and a feedstock for organic synthesis. In polymers/plastics, it may be evaluated as a co-monomer or olefin source in polyolefin production to tailor resin properties. In coatings and inks, it can function as a solvent or reactive diluent and as a processing aid in industrial formulations. It also serves as a precursor for specialty chemicals in various synthetic routes and can be used as a cleaning solvent/diluent in certain industrial formulations.
