- Description
OH-PEG3-Tos is a PEG linker with hydroxyl and tosyl functionalities at opposite ends. Its hydrophilic PEG spacer increases aqueous solubility, while the hydroxyl group provides a site for further derivatization. The tosyl group serves as a leaving group in nucleophilic substitution reactions. Applications include PROTAC synthesis and preparation of 3'-aminooxy oligonucleotide solid supports. The listed molecular formula is C13H20O6S, with purity of ≥95%.
