I. [Product Description]
Sulfadimethoxine-PEG-OPSS is a multifunctional organic intermediate. Through the precisely designed PEG segment, it achieves controllable coupling with the o-pyridyldisulfide group, possessing both excellent water solubility and reaction specificity. This compound can be used as a pharmaceutical intermediate for the construction of targeted delivery systems. The OPSS group can undergo directional cleavage in a reducing environment and is suitable for the catalyst-assisted reaction system in the field of bioconjugation.
