 | Hazard Information | Back Directory |  [Description]
  Tos-PEG2-CH2CO2tBu 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-PEG1-CH2-Boc is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1]. |  [IC 50]
