Acid-C5-tris-PEG3-azide is a branched PEG linker that offers three azide groups for reliable click chemistry with BCN, DBCO, or alkynes, and a carboxylic acid that couples with primary amines via activators like HATU. The PEG spacers elevate hydrophilicity, solubility, and biocompatibility, while the molecule's branched structure supports increased payload attachment in ADC applications. Reagent grade, for research use only.
