Boc-Amine Alkyne-PEG-acid, MW 5,000 is a protected amino polyPEG which can be reacted with azido group via copper catalyzed click chemistry to form a triazole linkage. The carboxylic acid is reactive with amine in the presence of HATU or EDC via formation of amide bond. Deprotection of the polymer can be done using HCl or TFA to yield a free amine which can be used for coupling with activated NHS ester. Reagent grade, for research purpose.
