I. [Product Description] 
NH2-PEG-IA (Amino-polyethylene glycol-iodoacetamide) is a multifunctional organic intermediate, possessing both the reactivity of amino groups and the ability of iodoacetamide to specifically bind to sulfhydryl groups. It can be used as an efficient coupling reagent or catalyst in the modification of biological macromolecules and the functionalization of material surfaces. Its PEG chain provides excellent water solubility and biocompatibility, making it suitable for the synthesis of pharmaceutical intermediates and the construction of complex molecular systems.
