Amino-PEG6-bis-PEG5-azide is a branched PEG linker designed for enhanced drug loading in ADC development. Its terminal amino group reacts with carboxylic acids, NHS esters, and carbonyls, while three azide groups facilitate click chemistry with DBCO, BCN, or alkynes. The hydrophilic PEG spacers enhance water solubility and biocompatibility. Reagent grade, for research use only.
