OTs-PEG1-NHCbz is a PEG linker containing a tosyl group and benzyl (Cbz) protecting group. The hydrophilic PEG spacer increases the water solubility of the compound in aqueous media. The tosyl group is a very good leaving group for nucleophilic substitution reactions. The benzyl protecting group can be removed via hydrogenolysis to form a free amine.
