I. [Product Description]
OPSS-PEG-glycine is a multifunctional organic intermediate that combines the high-efficiency thiol reactivity of the ortho-pyridyl disulfide bond (OPSS) with the excellent biocompatibility of the PEG chain. It is widely used in the fields of bioconjugation, polymer synthesis, and surface modification of nanomaterials. Its precise molecular design allows it to serve as an efficient catalyst carrier or pharmaceutical intermediate, meeting the requirements for complex chemical modifications.
