Polyethylene Glycol (PEGs & PEOs)

Ms-PEG8-Ms is a PEG derivative with two mesyl groups. The mesyl group is a good leaving group for nucleophilic substitution reactions. The hydrophilic PEG spacer increases solubility in aqueous media.

Ms-PEG8-t-butyl ester is a PEG derivative with a mesyl group and a t-butyl protecting group. Mesyl is a good leaving group and can participate in substitution reactions. The t-butyl group can be removed under acidic condtions. The hydrophilic PEG
