  • Applications

    1-Decen-4-yne (CAS 24948-66-1) is primarily used as a building block and intermediate in organic synthesis for specialty polymers and elastomers, where its alkyne functionality can be used to tailor polymer properties. It may serve as a reactive monomer or crosslinking precursor in coatings, inks, and adhesive formulations, enabling post-polymerization modification or improved network formation. The alkyne group also makes it suitable as a starting point for copper-catalyzed coupling reactions (for example Sonogashira routes) to access functional materials and conjugated structures. It is commonly evaluated as an intermediate in the synthesis of fine chemicals, including pharmaceutical and agrochemical intermediates, under appropriate controls. In industrial manufacturing contexts it is handled as a specialty chemical for formulation and synthetic routes, subject to local regulations and formulation limits.
