  • Applications

    4-Decyne (CAS 2384-86-3) is an internal alkyne hydrocarbon (C10) primarily used as an organic synthesis intermediate and building block for specialty compounds. In the materials field, it serves as a precursor for functional polymers and plastics, particularly for systems enabling cross-linking and click-chemistry–based formulations. In the coatings/inks and adhesives sectors, it may be exploited as a functional-building component for surface modification and engineered properties. Additionally, it can be evaluated in fragrance research as a potential odor-related intermediate or reference for scent-formulation work. Its use is subject to local regulations and formulation limits.
