N-Boc-PEG11-alcohol is a very popular PEG reagent containing a terminal Boc-protected amino and hydroxyl group. The Boc group can be deprotected under mild acidic conditions to form the free amine. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
