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. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
