- Description
Tos-PEG3-Tos is a bifunctional PEG linker with two tosyl groups joined through a PEG3 spacer. Its hydrophilic PEG segment supports aqueous solubility, while the tosyl groups serve as leaving groups in nucleophilic substitution reactions. These features enable further chemical modification in bioconjugation and organic synthesis. The molecular formula is C20H26O8S2, with a listed molecular weight of 458.546 and purity of ≥95%.
