CAS number：168640-82-2 molecular formula：C15H23N3O6S
Azide-PEG4-Tos is a PEG derivative containing an azide group and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. 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 substitution reactions.
