I. [Product Description]
PDP-PEG-COOH (Pyridyldithiopropionyl-Polyethylene Glycol-Carboxyl) is a multifunctional organic intermediate with excellent biocompatibility and chemical reactivity. The pyridyldithiopropionyl (PDP) group in its structure can serve as an efficient catalyst or connection site, the carboxyl group (-COOH) provides directional coupling ability, and the PEG segment endows the molecule with good water solubility and spatial tunability. It is widely used in the synthesis of pharmaceutical intermediates and the surface functionalization of materials.
