  • Applications

    Lauren-1-ene (CAS 72779-23-8) is primarily used as an industrial chemical intermediate and solvent, serving as a reactive feedstock for the synthesis of higher-value chemicals and specialty intermediates. It can function as a diluent or processing aid in coatings and inks, and may act as a monomer or comonomer in polymer production. It is also employed in adhesive formulations and cleaning products as a processing solvent, with additional applications evaluated under formulation limits and local regulations.
