I. [Product Description]
HZ-PEG-SPDP Hydrazide-Polyethylene Glycol-Dithiopyridine Disulfide is a multifunctional organic intermediate with dual reactivity of hydrazide groups and disulfide bonds. It can be used for bioconjugation, drug carrier construction, and polymer material modification. Its PEG segment significantly enhances water solubility and biocompatibility, and the dithiopyridine group supports controllable thiol coupling reactions. It is an ideal catalyst and linking molecule in fields such as protein modification and nanoparticle functionalization.
