Description

20-Hydroxy-3,6,9,12,15,18-hexaoxaicos-1-yl undec-10-enoate is a specialized polyethylene glycol (PEG) derivative featuring a terminal hydroxyl group and an unsaturated fatty acid ester chain. This bifunctional structure makes it a valuable intermediate for creating amphiphilic polymers and surface-active agents with tailored properties. It is primarily sought after by R&D chemists and formulators in the pharmaceutical, cosmetic, and advanced materials sectors for applications requiring precise molecular architecture and biocompatibility.

Application

• Pharmaceutical Excipient: Used as a solubilizer, emulsifier, or linker in drug delivery systems, including micelles, liposomes, and prodrugs.
• Polymer Synthesis: Serves as a key monomer or macromonomer for creating functionalized PEG-based hydrogels, coatings, and biodegradable polymers.
• Surface Modification: Employed to modify the surface properties of nanoparticles, quantum dots, and other nanomaterials to improve dispersion and biocompatibility.
• Cosmetic Formulations: Acts as an emollient or conditioning agent in high-performance skincare and haircare products.
• Bioconjugation: Utilized as a heterobifunctional crosslinker for attaching peptides, proteins, or other biomolecules to surfaces or carriers.
• Lubricant & Release Agent: Applied in specialized industrial formulations where a non-ionic, reactive surfactant is required.
