Description

11-Nonadecyn-1-ol is a high-purity, long-chain terminal alkyne alcohol with a defined molecular structure, offering a versatile building block for advanced organic synthesis. Its terminal alkyne and primary alcohol functional groups make it a valuable intermediate for constructing complex molecules through reactions like Sonogashira coupling and click chemistry. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty materials sectors who require precise molecular scaffolds for drug discovery, ligand development, and polymer modification.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the development of active pharmaceutical ingredients (APIs), particularly for creating novel compounds via coupling reactions.
• Agrochemical Research: Used in the synthesis of new crop protection agents and plant growth regulators that require specific long-chain hydrophobic moieties.
• Material Science: Acts as a monomer or cross-linking agent in the production of specialty polymers, coatings, and liquid crystals.
• Chemical Biology & Bioconjugation: Utilized in click chemistry applications (e.g., with azides) for labeling biomolecules, developing probes, and surface functionalization.
• Ligand Synthesis: Employed in the preparation of sophisticated ligands for catalysis and metal-organic frameworks (MOFs).
• Organic Synthesis Building Block: Provides a defined C19 chain for constructing complex natural product analogs and other fine chemicals.
