Description

11-Octadecyn-1-Ol is a long-chain fatty alcohol featuring a terminal alkyne group, making it a versatile bifunctional intermediate for organic synthesis. This unique structure is critical for introducing both hydrophobic alkyl chains and reactive sites for click chemistry and cross-coupling reactions into target molecules. It is primarily sought after by R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Serves as a key building block for synthesizing bioactive molecules, prodrugs, and lipid conjugates via its hydroxyl and alkyne functionalities.
• Agrochemical Synthesis: Used in the production of surfactants, adjuvants, and active ingredients that require specific lipid-like properties.
• Polymer & Material Science: Acts as a monomer or modifier for creating specialty polymers, surface coatings, and self-assembled monolayers (SAMs).
• Click Chemistry Substrate: The terminal alkyne group is ideal for copper-catalyzed azide-alkyne cycloaddition (CuAAC) reactions, a cornerstone of bioconjugation and material labeling.
• Lubricant & Surfactant Additive: Imparts specific rheological and surface-active properties when incorporated into formulations.
• Research & Development: A valuable tool in academic and industrial labs for exploring new synthetic pathways and material properties.
