Azide-PEG-amine TFA salt, MW 10,000 is a heterobifunctional PEGylation reagent with azide and amine end groups. The azide moiety can undergo click chemistry with an alkyne molecule via triazole bond formation. The amine can react with activated NHS ester to form a stable amide bond. The hydrophilic PEG chain increases the water solubility of the compound in aqueous media. Reagent grade, for research purpose.
