Acid-C5-bis-PEG3-DBCO serves as a versatile, branched PEG linker featuring two DBCO groups for reacting with azide-bearing compounds via click chemistry, and a carboxylic acid for amine conjugation (e.g., using HATU). Its PEG spacers enhance hydrophilicity, while the branched architecture increases ADC payload capacity. Reagent grade, for research use only.
