Hydroxy PEG

The structure of hydroxypolyethylene glycol is mainly composed of polyethylene glycol chain and hydroxyl group. The polyethylene glycol chain is composed of multiple ethylene glycol units and has good water solubility and biocompatibility. The presence of hydroxyl groups enables hydroxypolyethylene glycol to react with other molecules and participate in various chemical reactions, such as esterification, etherification and substitution reactions. It is widely used in biomedicine, drug delivery, tissue engineering and other fields.
