Description
PEG18 is a linear polyethylene glycol (PEG) polymer consisting of 18 ethylene glycol units and two terminal hydroxyl groups. The repeating ethylene glycol subunits provide flexibility and hydrophilicity, while the terminal hydroxyl groups serve as reactive sites for further chemical derivatization. Its extended PEG chain significantly enhances water solubility in aqueous media.
Applications
PEG18 is widely used in drug delivery, surface modification, and bioconjugation. The terminal hydroxyl groups allow for versatile functionalization, making it ideal for synthesizing hydrophilic linkers, enhancing solubility, and stabilizing biomolecules in pharmaceutical and biomedical research.
