1,1,1-Trifluoroethyl-PEG5-alcohol linker contains a trifluoroethyl and alcohol group. The trifluoroethyl group is a amide isostere and is used to interact with lysine and other primary amine groups in proteins, antibody and other molecules and surfaces. The hydroxyl group can be derivatized to other reactive functional group for conjugation. The hydrophilic PEG linkers increase the water solubility of the compound in aqueous media.
