Amino-PEG4-β-D-glucose is a hydrophilic bifunctional linker featuring a terminal primary amine and a β-D-glucose moiety. It is suitable for PROTAC synthesis, bioconjugation, and drug delivery applications. The amine group enables efficient amide coupling with carboxylic acids, while the PEG4 units improve solubility and flexibility. The glucose unit can improve pharmacokinetics and cellular uptake, making this linker ideal for constructing glyco-engineered or targeted therapeutic conjugates.
