Description

2,4,6,8,10,12,14,16,18-Nonaoxanonadecane is a high-purity polyethylene glycol (PEG) derivative, specifically a nonamer of ethylene oxide, valued for its precise molecular weight and consistent chain length. This compound serves as a critical building block and performance additive, offering superior control over solubility, viscosity, and biocompatibility in advanced formulations. It is essential for manufacturers in the pharmaceutical, specialty chemical, and advanced materials sectors seeking reliable, high-quality PEG intermediates.

Application

• Pharmaceutical Excipient: Used as a solubilizer, stabilizer, and carrier in drug delivery systems, including solid dispersions and parenteral formulations.
• Polymer Chemistry: Acts as a monomer or macromonomer for synthesizing precisely defined block copolymers and functionalized PEG derivatives.
• Surface Modification: Employed to create hydrophilic, protein-resistant coatings on biomedical devices and nanoparticles (PEGylation).
• Chemical Synthesis: Serves as a versatile linker or spacer molecule in organic synthesis and bioconjugation applications.
• Personal Care & Cosmetics: Functions as a non-irritating humectant and viscosity modifier in high-performance skincare products.
• Lubricants & Functional Fluids: Used as a base or additive in specialty lubricants requiring high thermal stability and low volatility.
