Acid-PEG1-tris-PEG3-azide serves as a branched PEG linker featuring three azide groups to partake in click chemistry reactions with BCN, DBCO, and alkynes, and a carboxylic acid that reacts with primary amines in the presence of activators like HATU. The PEG spacers enhance the compound's hydrophilicity, improving solubility and biocompatibility. Branched linkers allow for more payload attachment to ADC. Reagent grade, for research use only.
