252881-74-6 - Reference Information
| overview | polyethylene glycol (Polyethyleneglycol,PEG) is formed by ring-opening polymerization of ethylene oxide, and the ratio of oxygen element to carbon element in its molecular formula is as high as 1:2. This unique structure gives it excellent water solubility and biocompatibility. Coupling polyethylene glycol to the surface of polypeptide or protein drugs can increase the water solubility of the drug, prolong the half-life of the drug, and reduce the immunogenicity of the drug. In addition, polyethylene glycol has low toxicity and can be excreted by the kidneys without accumulating in the body. |
| use | 12-amino -4,7,10-tert-butyl trioxododecanoate can be used as an intermediate in pharmaceutical synthesis, such as preparing amino polyethylene glycol propionic acid. |
