Intermediate & Activated PEGs CAS NO.80506-64-5

PEG derivatives are known not only to increase drug circulation time, solubility and stability but also reduce immunogenicity and toxicity when attached to a drug. These potential advantages allow many applications such as Pegylated-protein/peptide drugs, -hydrogels, -liposomes for pharmaceutical uses and Pegylated-hemoglobin as oxygen/CO2 carrier.

We supply various polyethyleneglycol derivatives of high quality available at commercial scale and cGMP grade.
