N-(Amine-PEG4)-N-bis(PEG4-acid), TFA salt is a branched PEG linker with two terminal carboxylic acid groups that can react with primary amine groups in the presence of activators such as HATU and a terminal amine group which can be used to build a wide variety of bonds. The PEG4 spacers enhance the aqueous solubility of the compound. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research purpose.
