I. [Product Introduction]
NH2-PEG-Biotin is a multifunctional organic intermediate with both amino-reactive activity and specific biotin-binding ability. It is widely used in the construction of catalyst carriers in bioconjugation reactions. Its PEG segment endows the molecule with excellent water solubility and steric hindrance effect, making it suitable for the synthesis of pharmaceutical intermediates and complex molecular assembly systems.

II. [Product Details]
