Benzyl-PEG4-bromide is a PEG linker containing a benzyl protecting group, which can be deprotected under hydrogenation catalytic conditions. The bromide (Br) is a very good leaving group for nucleophilic substitution reactions (e.g., thiol, amine). The hydrophilic PEG linker improves the water solubility of the compound.
