Azide-PEG-CH2CO2H, MW 5,000 is a click chemistry PEG polymer, azide undergoes click chemistry with alkyne group, such as DBCO or BCN molecules. Carboxylic acid can conjugate with amine containing molecules such as protein, peptide in the presence of coupling reagent, HATU or EDC to form a stable amide bond. Reagent grade, for research purpose.

Azide-PEG-CH2CO2H, MW 10,000 is a heterobifunctional polyPEG with azide and carboxylic acid on each end. Azide reacts with alkyne through click chemistry and has found increasing applications in medicinal chemistry. The carboxylic group react with amine containing molecules to form an amide bond. Reagent grade, for research purpose.

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.

Azide-PEG-alcohol, MW 1,000 is an azide and alcohol functionalized PEG. Azide is a very popular moiety for copper-catalyzed or copper-free click-chemistry with many alkyne-containing molecules. Reagent grade, for research purpose.
