Azide-PEG4-Tos,cas168640-82-2

 Azide-PEG4-Tos/Azide-PEG4-Tosylate/N3-PEG4-Tos/N3-PEG4-Tosylate linker containes an azide group and a tosyl group. The azide group can react with alkyne, BCN, DBCO via Click Chemistry to yield a stable triazole linkage. The tosyl group is a good leaving group for nucleophilic substitutions. The PEG spacer increases the aqueous solubility of the resulting compound.This type of compound may be utilized in bioconjugation chemistry, where the azide group can participate in click chemistry reactions to link with other molecules or surfaces, and the tosylate group may be involved in specific chemical reactions.
