Description

3,6,9,12,15,18,21,24,27,30,33,36-Dodecaoxaoctatetracontan-1-Ol is a high-purity polyethylene glycol (PEG) derivative, specifically a long-chain PEG monoalcohol, valued for its exceptional hydrophilicity and non-ionic surfactant properties. This compound is a critical intermediate and functional additive, enabling precise control over solubility, viscosity, and biocompatibility in advanced formulations. It is essential for manufacturers in the pharmaceutical, biotechnology, and specialty chemical industries seeking reliable, high-quality PEGylated components for research, development, and production.

Application

• Pharmaceutical Excipient & Drug Conjugation: Used as a linker or carrier in PEGylation technology to improve the solubility, stability, and circulation time of therapeutic proteins and peptides.
• Biomaterial & Hydrogel Synthesis: Serves as a key monomer or cross-linking agent for creating biocompatible hydrogels used in tissue engineering, wound dressings, and controlled drug delivery systems.
• Surface Modification & Functionalization: Applied to modify the surface properties of nanoparticles, liposomes, and medical devices to enhance stealth characteristics, reduce protein adsorption, and improve biocompatibility.
• Specialty Polymer & Resin Production: Acts as a hydrophilic building block in the synthesis of polyurethanes, polyesters, and other polymers requiring tailored hydrophilicity and flexibility.
• Lubricant & Processing Aid: Functions as a non-ionic lubricant and viscosity modifier in specialty industrial fluids, coatings, and personal care formulations.
• Analytical & Diagnostic Reagents: Utilized in the preparation of chromatography standards, buffer components, and reagents for diagnostic assays and biochemical research.
