Ethanol, 2-[2-(2-hydroxyethoxy)ethoxy]-, 1-(4-Methylbenzenesulfonate) Chemical Properties,Uses,Production
Description
PEG3-Tos is a PEG linker containing a hydroxyl group and 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.
