  • Applications

    2-Pentadecyn-1-ol (CAS number: 2834-00-6) is a long-chain alkyne alcohol that functions as a versatile synthetic intermediate. In industrial manufacturing, it is used to introduce terminal alkyne functionality into organic molecules, enabling subsequent click-chemistry or coupling reactions. In polymers and plastics, it serves as a building block for alkynyl-functional monomers and for surface-modification reagents in advanced coatings and adhesives. In coating and ink formulations, it acts as a reactive chain-end or crosslinkable modifier to improve adhesion and durability. In pharmaceutical and agrochemical R&D, it is employed as a synthetic intermediate for alkynyl-containing compounds, while in fragrance and cosmetics research it may be evaluated as a specialty intermediate for scent-related or formulation applications.
