Description

3,6,9,12,15,18-Hexaoxaicosane-1,20-Diyl Di(Undec-10-Enoate) is a specialized polyethylene glycol (PEG) derivative featuring terminal reactive unsaturation, making it a valuable functionalized linker and cross-linking agent. This compound matters for its ability to introduce hydrophilic PEG spacers while providing terminal alkene groups for further chemical modification, such as thiol-ene click chemistry or polymerization. It is primarily needed by researchers and manufacturers in the pharmaceutical, biomedical, and advanced materials sectors for applications like polymer synthesis, bioconjugation, and hydrogel formation.

Application

• Polymer & Material Science: Acts as a difunctional macromonomer or cross-linker in the synthesis of hydrogels, networks, and functional polymers via radical or photo-initiated polymerization.
• Bioconjugation & Drug Delivery: Serves as a hydrophilic, biocompatible PEG spacer to conjugate drugs, peptides, or targeting ligands to carriers, enhancing solubility and circulation time.
• Surface Modification: Used to create PEGylated surfaces with reactive terminal groups for subsequent immobilization of biomolecules, reducing non-specific binding.
• Click Chemistry Reagent: The terminal undecenoate groups participate efficiently in thiol-ene reactions, a cornerstone of click chemistry, for precise and modular assembly.
• Lubricant & Surfactant Intermediate: Functions as a key intermediate in the production of specialized lubricants and non-ionic surfactants with tailored properties.
• Research & Development: A critical tool in R&D for exploring new polymeric architectures, drug delivery systems, and biomaterials.
