Chemical Structure

Key Applications

• Fatty alcohol building block: 11-Henicosanol is a long-chain fatty alcohol used as a precursor for the preparation of esters, ethers, and other aliphatic derivatives in organic synthesis. It serves as an upstream intermediate in Long-Chain Ethers and Fatty Alcohol Derivatives for Specialty Synthesis, where extended alkyl chains provide hydrophobicity and functional performance.

• Hydrophobic chain introduction: The long alkyl chain enables incorporation of lipophilic segments into functional molecules, supporting solubility tuning, surface activity, and molecular stability. This function relates to the broader long-chain ether and fatty derivative application category.

• Fine chemical intermediate: Utilized in the synthesis of specialty chemicals, surfactants, and functional materials where long-chain alcohols serve as key structural components.

• Pharmaceutical and functional modification: Applied in medicinal chemistry for introducing lipophilic chains to adjust molecular properties such as membrane interaction and bioavailability.

• Laboratory research: Used in academic and industrial research for studying long-chain alcohol reactivity and developing new synthetic methodologies.

• Process development: Supports route optimization and scale-up in synthesis processes requiring reliable long-chain fatty alcohol intermediates.

11-Henicosanol is used as an upstream intermediate in the Long-Chain Ethers and Fatty Alcohol Derivatives application category and is part of our broader portfolio of Ethers for Pharmaceutical Intermediates & Specialty Synthesis, covering fatty alcohol precursors, long-chain ether derivatives, and specialty functional materials.

• SDS and COA support: Full safety data sheets and certificates of analysis are provided with each shipment to facilitate regulatory review and quality assurance processes.

• Packaging and technical service: Flexible packaging options including 25L/200L HDPE drum, with responsive technical communication for customer-specific needs.
