I. [Product Description]
OPSS-PEG-serine is a multifunctional organic intermediate. Its core structure integrates the high-efficiency coupling activity of o-pyridyl disulfide (OPSS), the excellent water solubility of polyethylene glycol (PEG), and the biocompatibility of serine. It is suitable for the modification of biological macromolecules, the synthesis of polymer materials, and the construction of catalytic systems. This compound can achieve precise coupling through the thiol-disulfide exchange reaction, making it an ideal choice for constructing stable complexes or functionalized carriers.
