HOOC-PEG-SH (MW 5000) (HOOC-PEG-Thiol (MW 5000)) is a reactive thiol PEG derivative with a terminal carboxyl group. The carboxyl group can react with amine or hydroxyl groups to form a stable amide bond or an unstable ester bond. The PEG linkage between the thiol and carboxyl groups has good water solubility, flexible linker distance and higher stability[1].
