Properties

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.
