Description

4-Undecen-1-ol is a versatile, medium-chain unsaturated fatty alcohol with a terminal double bond and a primary hydroxyl group. This unique bifunctional structure makes it a valuable intermediate for synthesizing a wide range of specialty chemicals, including fragrances, plasticizers, and surfactants. It is particularly sought after by manufacturers in the flavor & fragrance, polymer, and fine chemical industries for its ability to introduce both hydrophobicity and reactive sites into target molecules.

Application

• Fragrance & Flavor Intermediate: Serves as a key building block for the synthesis of musk-like odorants, fruity esters, and other specialty aroma chemicals.
• Polymer Modification: Used as a comonomer or chain transfer agent to introduce long alkyl chains and unsaturation into polymers, modifying flexibility and properties.
• Surfactant & Lubricant Synthesis: Acts as a hydrophobic precursor for producing non-ionic surfactants, emulsifiers, and synthetic lubricant base stocks.
• Organic Synthesis: A valuable chiral pool reagent and intermediate in pharmaceutical and agrochemical research for constructing complex molecular architectures.
• Crosslinking Agent: The terminal double bond allows it to function as a crosslinker in resin and coating formulations, enhancing durability.
• Plasticizer Production: Used to create ester-based plasticizers that can improve the low-temperature performance and flexibility of PVC and other polymers.

Quality Control

Our 4-Undecen-1-ol is produced under strict quality management protocols. Each batch is characterized using advanced analytical techniques including GC, HPLC, and NMR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical specifications is provided with every shipment to guarantee it meets your precise application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its susceptibility to oxidation, minimize headspace and avoid prolonged exposure to air.
