Homobifunctional PEG and Oligoethylene Glycols (17)

Homobifunctional polyethylene glycol is a PEG molecule containing two identical reactive groups, enabling it to create crosslinks or bonds with other molecules or materials. It is commonly utilized in the development of multifunctional nanocarriers or crosslinked polymers. Oligopolyethylene glycol (e.g., PEG-2 and PEG-4) primarily serves as a solvent and permeation enhancer, facilitating the dissolution of active ingredients, improving stability and solubility, enhancing the permeability and absorption of oral drugs, and thereby increasing bioavailability.
