  • Applications

    9-Undecenenitrile, (9E)- (CAS 131379-26-5) is primarily used as an organic intermediate in industrial manufacturing. It can function as a building block or co-monomer in the synthesis of specialty polymers and nitrile-containing resins. In coatings and inks, it serves as a reactive intermediate for resin and surface-coating formulations. It is also employed as a component or precursor in adhesive formulations that leverage long-chain nitrile chemistry. All applications are subject to local regulations and formulation limits.
