I. [Product Description]
OPSS-PEG-VS is a multifunctional organic intermediate that combines the dynamic exchange properties of the ortho-pyridyl disulfide bond and the high-efficiency coupling activity of the vinyl sulfone group. It is widely used in the fields of bioconjugation and material modification. The compound enhances water solubility through a precisely designed PEG segment and can be used as a pharmaceutical intermediate or catalyst carrier to meet the requirements of directional modification in complex chemical reactions.
