Bis-dPEG®5, half benzyl half NHS ester, product number QBD-10237, is a short, discrete PEG (dPEG®) modification reagent designed for stepwise reactions with amines. Both ends of the single molecular weight PEG linker terminate with propionic acid groups. One end is functionalized as the N-hydroxysuccinimidyl (NHS) ester, while the other acid end is protected as the benzyl ester. The benzyl ester can be removed using hydrogen with a palladium catalyst.
The dPEG®5 linker increases conjugates’ hydrodynamic volume and hydrophilicity. QBD-10237 is useful for crosslinking amines under controlled conditions, modifying peptides at N-termini or amine-functionalized side chains, and building supramolecular constructs that require flexible, hydrophilic spacers.
