Polyethylene Glycol (PEGs & PEOs)

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

m-PEG8-NHS ester.

m-PEG8-NHS ester.

m-PEG8-NHS ester.

m-PEG8-t-butyl ester is a PEG derivative containing a t-butyl ester. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The hydrophilic PEG spacer increases solubility in aqueous media.

m-PEG8-thiol is a PEG derivative containing a thiol group. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydrophilic PEG spacer increases solubility in aqueous media.

m-PEG8-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.
