I. [Product Introduction]
OPSS-PEG-Biotin is a multifunctional organic intermediate that achieves controllable cleavage characteristics through the ortho-pyridyldisulfide bond (OPSS), combining the excellent water solubility of polyethylene glycol (PEG) with the high-affinity binding ability of biotin. This compound has important application value in bioconjugation, nanomaterial modification, and catalytic systems, and can be used as a pharmaceutical intermediate for the construction of target molecules.
