Branched PEG derivatives, also known as "Y-shaped" PEG derivatives, contain two linear methoxy PEG chain attached to a central core. The sterically bulky structure of these "Y-shaped" PEG derivatives will facilitate the single point attachment of the modified molecules.
Branched PEG Derivatives are synthesized via nucleophilic substitution of multifunctional initiators with polyethylene glycol chains. These hyperbranched structures enhance solubility and bioavailability compared to linear analogs.
Store under dry inert atmosphere below 25°C. Avoid direct contact during synthesis due to potential irritancy. Clinical use requires rigorous purity verification to prevent immunogenicity.
