What is Tetraethylene glycol di-p-tosylate?
Description
Tos-PEG5-Tos is a PEG linker containing two tosyl groups. The hydrophilic PEG spacer increases solubility in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions.
The Uses of Tetraethylene glycol di-p-tosylate
Tetraethylene glycol di(p-toluenesulfonate) was used in the preparation of donor-spacer-acceptor podand system, dual channel fluorosensor for Li+, Mg2+ and Ca2+.
