I. [Product Description]
NH2-PEG-Dansyl is a multifunctional organic intermediate prepared through the efficient coupling reaction between amino groups and dansyl chloride. It combines the fluorescence labeling function with the biocompatibility of the PEG chain. This compound can be used as a pharmaceutical intermediate for biomolecule modification. The PEG segment endows it with excellent water solubility and steric hindrance effect. Meanwhile, it can also serve as a catalyst carrier to enhance the reaction efficiency in specific reaction systems.
