  • Applications

    (2E,8E)-deca-2,8-dien-4,6-diyn-1-ol (CAS 505-98-6) is a functional organic building block featuring two conjugated double bonds and two diynes with a terminal hydroxyl group. In industry, it is primarily used as an intermediate in organic synthesis, enabling introduction of conjugated diyne motifs and enabling subsequent functionalization. It is commonly evaluated as a monomer or crosslinking reagent in specialty polymers and coatings/inks formulations to impart network formation and enhanced thermal and mechanical properties. It can also serve as a precursor for adhesive formulations through crosslinking chemistry. Additionally, due to its conjugated framework, it is explored as a precursor for functional materials in electronics or optoelectronic applications. Depending on the process and regulatory requirements, its use is subject to local regulations and formulation limits.
