I. [Product Description]
Aminooxy-PEG-Dansyl (Ammonium Methyl-PEG-Dansyl Chloride) is a multifunctional organic intermediate that combines the active groups of aminooxy and dansyl chloride. It achieves excellent solubility and biocompatibility through the PEG chain. This compound can serve as an efficient catalyst or cross-linking agent, and is widely used in fields such as bioconjugation, material surface modification, and fluorescent labeling. It is a key functional reagent for the development of pharmaceutical intermediates.

II. [Product Details]
