CAS number：2055042-83-4 molecular formula：C21H39BrO9
Propargyl-PEG9-bromide is a PEG derivative containing a propargyl group and a bromide group. The propargyl group can be reacted with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.
