CAS number：2179113-08-5 molecular formula：C47H88O23S
PEG21-Tos is a PEG derivative containing a hydroxyl group with a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The tosyl group is a very good leaving group for nucleophilic substitution reactions.
