Bromo-PEG1-azide

Bromo-PEG1-azide is a bifunctional PEG linker with a bromide (Br)group and an azide(N3) group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The bromide (Br) is a good leaving group for nucleophilic substitution reactions.
