m-PEG-azide

m-PEG-Azide, an azide-containing PEG polymer, is a monofunctional PEG derivative that can be used to modify proteins, peptides, and other materials. For the PEGylation of alkynes under simple and fast reaction conditions, even in aqueous environments. The azide group of methoxyPEG azides can be reduced to amines by hydrogenolysis.
