Epoxide glycidyl ether PEG

What is Epoxide Glycidyl Ether PEG?

Epoxide glycidyl ether PEG is a functional polymer that can be produced by the reaction of ethylene oxide and polyethylene glycol. PEG Epoxide can be modified with 4-Arm, 8-Arm, etc. Epoxide glycidyl ether PEG is easy to use and handle in aqueous systems and tends to have low toxicity and immunogenicity to organisms.

What is Epoxide Glycidyl Ether PEG

Examples of Epoxide Glycidyl Ether PEG

4-Arm PEG-Epoxide

4-Arm PEG-Epoxide is a multi-armed PEG derivative with an epoxide at each end of the four arms connected to the pentaerythritol core. It is usually a solid powder or granule that needs to be protected with an inert gas, frozen, and dissolved in some organic reagent, such as dimethyl sulfoxide and dimethylformamide. The terminal epoxide is usually used in nucleophilic addition reactions to change the functional groups. Tetra-armed PEG derivatives have a variety of reactive groups that allow modification of proteins, peptides and other materials by their functional groups.

8-Arm PEG-Epoxide

Each of the eight arms of 8-Arm PEG-Epoxide has an epoxy group attached to a hexaglycerol core. The eight-arm PEG derivatives have a variety of reactive groups and can be used to modify a wide range of materials. The terminal epoxides are commonly used in nucleophilic addition reactions to modify functional groups.


Epoxide-PEG-Epoxide is a linear polymer containing epoxy groups at both ends of the molecular chain and is soluble in water, DMSO, and DMF. It is typically used to cross-link PEG molecules containing amines or hydroxyls to the surface of the substrate via epoxide ring-opening reactions. The reaction of Epoxide-PEG-Epoxide with a drug modifies the dispersion and solubility of the drug molecule in solution.

Mode of Epoxide Glycidyl Ether PEG Binding

  • Hydroxylation: The epoxide glycidyl ether PEG reacts with hydroxyl compounds to form hydroxylated PEG compounds, which can be used as water-soluble polymers, thickeners, surfactants, etc.
  • Amination: Aminated PEG compounds are formed when glycidyl ether PEG reacts with amine compounds, and are commonly used in the preparation of drug delivery systems, polyelectrolytes, and modifiers of biologically active substances.
  • Carboxylation: Carboxylated PEG compounds can be generated from epoxide glycidyl ether PEG by reacting with carboxylic acids or anhydrides.
  • Sulfurization: The sulfurized PEG compounds produced by epoxiding glycidyl ether PEG are commonly used in adhesives and elastomers.
  • Cyclization: PEG glycidyl ethers can be cyclized by reacting with reactive functional groups, such as reactive functional groups to form cyclized PEG compounds.

Applications of Epoxide Glycidyl Ether PEG

Pharmaceutical Field
