I. [Product Description]
OPSS-PEG-NH2 is a multifunctional organic intermediate that combines the high reactivity of ortho-pyridyl disulfide (OPSS) with the excellent biocompatibility of polyethylene glycol (PEG). It is widely used in bioconjugation, nanomaterial preparation, and catalytic reaction systems. Its amino-terminal and cleavable disulfide bond design make it an efficient crosslinking agent or pharmaceutical intermediate, suitable for precise molecular modification and the development of functionalized materials.
