Thiol-PEG3-alcohol linker contains a thiol group and a hydroxyl group. The PEG spacer increases the aqueous solubility of the resulting compound. The thiol group reacts with maleimide, OPSS, vinylsulfone and transition metal surfaces including gold, silver, etc. The hydroxyl group enables further derivatization or replacement with other reactive functional groups.
