| | Tos-PEG2-t-butyl ester Usage And Synthesis |
| Description | Tos-PEG2-t-butyl ester is a PEG linker containing a t-butyl ester and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The t-butyl protected carboxyl group can be deprotected under acidic conditions. The tosyl group is a very good leaving group for nucleophilic substitution reactions. | | Uses | Tos-PEG2-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. | | IC 50 | PEGs; Alkyl/ether | | References | [1] Snaebjornsson MT, et al.
