Aldehyde-PEG4-bis-PEG4-alkyne functions as a branched PEG linker with an aldehyde group that is reactive with a hydrazide or amine group to form a hydrazone or imine bond, respectively. The alkyne groups partake in click chemistry reactions with azide-containing moieties. The PEG linkers improve the water solubility of the compound. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research use only.
