Description

2,5,8,11,14,17,20,23,26,29,32-Undecaoxatritriacontane is a high-purity polyethylene glycol (PEG) derivative, specifically a long-chain PEG ether, valued for its exceptional solubility, low toxicity, and non-ionic surfactant properties. This compound serves as a crucial building block and performance additive in advanced formulations requiring precise molecular weight control and consistent chemical behavior. It is essential for manufacturers in the pharmaceutical, specialty chemical, and advanced materials sectors seeking reliable, high-quality raw materials for research and production.

Application

• Pharmaceutical Excipient: Used as a solubilizer, stabilizer, and carrier in drug delivery systems, including for poorly soluble APIs.
• Polymer & Material Science: Acts as a monomer or macromonomer for synthesizing specialized polyethers, hydrogels, and functional polymers.
• Surface Modification Agent: Employed to create hydrophilic, protein-resistant coatings on medical devices, sensors, and nanoparticles (PEGylation).
• Specialty Chemical Intermediate: Serves as a key starting material for synthesizing complex non-ionic surfactants and emulsifiers.
• Lubricant & Plasticizer: Functions as a high-performance lubricant and processing aid in specialized industrial applications.
• Analytical & Research Chemistry: Utilized as a standard or reagent in chromatographic methods and biochemical research.
