| Tri(Ethylene Glycol) DI-P-Toluenesulfonate Usage And Synthesis |
Description | Tos-PEG4-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. | Chemical Properties | WHITE POWDER | Uses | Tri(ethylene glycol) di-p-toluenesulfonate is used in the synthesis of 1-[4-(1,4,7,10-tetraoxa-13-aza-cyclopentadec-13-yl)-phenyl] ethanone. | Synthesis |
2,2'-[1,2-ethanediylbis(oxy)]bisethanol and p-toluenesulfonyl chloride can be used as raw materials for the synthesis of Tri(Ethylene Glycol) DI-P-Toluenesulfonate.
