Polyethylene Glycol (PEGs & PEOs)

m-PEG6-Tos is a PEG derivative containing a tosyl group. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.

m-PEG7-(CH2)3-alcohol is a PEG derivative containing a hydroxyl group. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The hydrophilic PEG spacer increases solubility in aqueous media.
