Thiol-PEG3-phosphonic acid ethyl ester linker contains thiol and phosphonic acid ethyl ester. The thiol can be reacted with maleimides, disulfides, haloacteamides and thiols. It also shows strong affinity to transition metal surfaces. Both thiol and phosphonic acid ethyl ester are used for surface modification. The hydrophilic PEG linker can increase the solubility of a compound in aqueous media and improve the hydrophilicity of the surfaces.
