Nonaethylene Glycol Monomethyl Ether丨CAS 6048-68-6

Nonaethylene glycol monomethyl ether is a polyether compound widely used as a solvent, surfactant, and intermediate in chemical synthesis. Its long ethylene glycol chain terminated with a methyl ether group provides both hydrophilicity and moderate lipophilicity, making it effective in solubilizing polar and nonpolar compounds. It is commonly employed in the preparation of PEGylated molecules, including drugs, peptides, and polymers, where it enhances solubility, stability, and bioavailability. It also serves as a building block for detergents, emulsifiers, and dispersants, and finds applications in cosmetic and personal care formulations as a solubilizer and moisturizer. In organic synthesis, it is used as a reaction medium or co-solvent for sensitive compounds, and as a precursor for functionalized polymers, surfactants, and lubricants. Its versatility allows it to be applied across pharmaceuticals, materials science, and industrial chemical processes.

This compound provides multiple advantages in chemical, pharmaceutical, and materials applications. Its hydrophilic PEG chain improves solubility of poorly soluble molecules in aqueous and mixed solvents, enabling higher concentrations and more uniform formulations. The methyl ether end provides chemical stability, preventing unwanted reactions at the terminal hydroxyl site, which is valuable in multi-step syntheses. It has low volatility and high thermal stability, making it safe and easy to handle in laboratory and industrial settings. In PEGylation applications, it enhances pharmacokinetic and pharmacodynamic properties of therapeutic molecules by increasing solubility, reducing aggregation, and extending circulation time. Its amphiphilic nature also makes it a useful emulsifier, dispersant, or co-solvent in formulations that require stable mixtures of hydrophilic and hydrophobic components. Overall, it provides reliability, flexibility, and improved performance in research and manufacturing workflows.
