| | Tetraethylene glycol di-p-tosylate Usage And Synthesis |
| 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. | | Uses |
Tetraethylene glycol di(p-toluenesulfonate), also known as Tetraethylene glycol di-p-tosylate, was used in the preparation of donor-spacer-acceptor podand system, dual channel fluorosensor for Li+, Mg2+ and Ca2+.
