What is PEG

Different molecular weight polyethylene glycol has different morphology.

Polyethelene glycol (PEG) is a synthetic, hydrophilic, biocompatible polyether, which is consist of a (−O−CH2−CH2−) backbone. PEG is widely used in various fields, from industrial manufacturing to medicine. Its structure is commonly expressed as H−(O−CH2−CH2)n−OH. Depending on the molecular weight, PEG is also known as polyoxyethylene (POE) or polyethylene oxide (PEO). PEGs can be synthesized in linear, branched, Y-shaped, or multi-arm geometries. PEGs can be activated by replaing the terminal hydroxyl end group with various reactive functional end groups enabling crosslinking and conjugation chemistries.

Application of PEG

PEG is a kind of liquid or a low-melting solid obtained by ethylene oxide polymerization. PEG has a wide range of molecular weights and is widely used in various fields.
