CAS number：2055024-42-3 molecular formula：C19H37N3O11S
Azido-PEG3-Sulfone-PEG4-acid is a PEG derivative containing one azide group with a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) forming a stable amide bond. The azide group enables Click Chemistry. The hydrophilic PEG spacer increases solubility in aqueous media.
