Synonyms: Polyethylene glycol octadecyl ether

C18-PEG-OH is a PEG derivative modifier with C18 hydrocarbon chain at one end and hydroxyethyl at the other end. The simultaneous presence of polar groups and non-polar groups makes it a useful amphiphilic surfactant. As a PEG modifier, C18-PEG-OH helps to improve the solubility and stability of modified biomolecules, while reducing the immunogenicity of peptides and proteins, and inhibiting charged molecules on the modified surface Of non-specific binding. At present, C18-PEG-OH has broad application prospects in many fields such as peptide synthesis, polymer synthesis, organic synthesis, targeted drug delivery, and sustained and controlled release of drugs. In addition, as an excellent surfactant, it has important significance in the formation of micelles and the directional delivery of drugs.
