- Description
Tos-PEG4-Tos is a bifunctional PEG linker with two tosyl groups joined by a PEG4 spacer. These groups act as leaving groups in nucleophilic substitution reactions, allowing chemical modification for bioconjugation and organic synthesis. The hydrophilic PEG segment enhances solubility in aqueous environments.
Also named Tetraethylene glycol di(p-toluenesulfonate), this compound is listed among PROTAC linkers and polymer PEG reagents. Its molecular formula is C22H30O9S2, with molecular weight 502.6 and listed purity ≥95%.
