Benzyl-PEG5-amine linker contains a benzyl protecting group and a free amine group. The primary amine can react with carboxylic acids, activated NHS esters and other carbonyl compounds. The benzyl groups can be removed under mild condition to form an alcohol for further derivatization. The hydrophilic PEG linkers increase the solubility of a compound in aqueous media.
