Azido-PEG2-bis-PEG3-amine is a branched PEG linker that boosts drug loading in ADC development. Its terminal amino groups react with carboxylic acids, NHS esters, and carbonyls, while the azide moiety facilitates click chemistry with DBCO, BCN, or alkynes. Hydrophilic PEG spacers further enhance water solubility and biocompatibility. Reagent grade, for research use only.
