Description

3,6,9,12,15-Pentaoxanonadecan-1-Ol is a high-purity polyethylene glycol (PEG) derivative, specifically a monomethyl ether of a pentameric PEG chain. This compound is valued for its precise molecular structure and consistent quality, making it a critical intermediate and functional additive in advanced manufacturing. It is primarily utilized by industries requiring controlled hydrophilicity, solubility enhancement, and non-ionic surfactant properties, such as pharmaceuticals, specialty polymers, and advanced material science.

Application

• Pharmaceutical Intermediate: Used in the synthesis of prodrugs, PEGylated biologics, and drug delivery systems to improve solubility and pharmacokinetics.
• Polymer & Resin Modification: Acts as a reactive monomer or plasticizer in the production of polyurethanes, epoxy resins, and other specialty polymers to impart flexibility and moisture resistance.
• Surface Active Agent: Functions as a non-ionic surfactant, emulsifier, or wetting agent in formulations for coatings, inks, and agrochemicals.
• Chemical Synthesis Building Block: Serves as a versatile spacer or linker molecule in organic synthesis and bioconjugation chemistry.
• Personal Care & Cosmetics: Employed as a humectant and viscosity modifier in high-performance skincare and cosmetic formulations.
• Lubricant & Functional Fluid: Used as a base or additive in synthetic lubricants and heat transfer fluids due to its thermal stability and low volatility.
