I. [Product Description]
CHO-PEG-Dansyl (Aldehyde-Polyethylene Glycol-Dansyl chloride) is a multifunctional organic intermediate, which combines the reactivity of aldehyde groups with the fluorescence properties of dansyl chloride. It is suitable for bioconjugation reactions and the modification of nanomaterials. Its polyethylene glycol (PEG) chain can significantly enhance the water solubility and stability of the product, and it has important application values in the synthesis of pharmaceutical intermediates and the construction of catalyst carriers.
