Description

5-Undecyn-1-ol is a terminal alkyne alcohol with a linear carbon chain, serving as a versatile building block in organic synthesis. Its unique structure, featuring both a hydroxyl group and a terminal alkyne, makes it a valuable bifunctional intermediate for constructing more complex molecules. This compound is particularly relevant for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries who require high-purity intermediates for coupling reactions, polymer synthesis, and material science applications.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring alkyne moieties for click chemistry or as structural components.
• Agrochemical Synthesis: Serves as a key precursor in the development of novel pesticides, herbicides, and plant growth regulators.
• Polymer & Material Science: Acts as a monomer or chain extender in the production of specialty polymers, coatings, and advanced materials with tailored properties.
• Liquid Crystal & OLED Materials: Utilized in the synthesis of organic electronic materials, where its molecular structure can influence mesomorphic and optoelectronic properties.
• Cross-Coupling Reactions: A valuable substrate in Sonogashira, Glaser, and other palladium-catalyzed coupling reactions to form carbon-carbon bonds.
• Surface Modification & Linker Chemistry: The terminal alkyne group enables attachment to surfaces or biomolecules, useful in bioconjugation and sensor development.
• Fragrance & Flavor Chemistry: Can be used as an intermediate for synthesizing specific aroma compounds.
• Research & Development: Employed in academic and industrial R&D labs as a standard or custom building block for exploratory synthetic chemistry.

Quality Control

Our 5-Undecyn-1-ol is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (IR, NMR), to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality systems are designed to meet the stringent requirements of research and industrial-scale applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, open flames, and strong oxidizing agents. For long-term storage, consider storing under an inert atmosphere (e.g., nitrogen or argon) to prevent potential oxidation.
