| | PEG21-Tos Usage And Synthesis |
| Description | PEG21-Tos is a PEG linker containing a hydroxyl group with a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The tosyl group is a very good leaving group for nucleophilic substitution reactions. | | Uses | PEG20-Tos is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. | | IC 50 | PEGs | | References | [1] An S, et al.
