I. [Product Description] 
IA-PEG-COOH (Iodoacetyl-Polyethylene Glycol-Carboxyl) is a multifunctional organic intermediate that combines the high reactivity of the iodoacetyl group with the excellent water solubility of the PEG segment. It can be used as an efficient catalyst support or pharmaceutical intermediate and is widely used in the fields of bioconjugation, material modification, and nanotechnology. Its bifunctional design supports directional coupling, providing precise connection sites for the construction of complex molecules.
