I. [Product Description]
OPSS-PEG-SH is a multifunctional organic intermediate with dual reactive sites of ortho-pyridyl disulfide (OPSS) and thiol (-SH). It is suitable for the directional coupling and controllable modification of biological macromolecules. Its PEG segment endows it with excellent water solubility and biocompatibility, and it has important application value in the fields of catalyst-mediated coupling reactions and surface functionalization of nanomaterials.
