I. [Product Description]
SH-PEG-Dansyl (Thiol-Polyethylene Glycol-Dansyl Chloride) is a multifunctional organic intermediate that combines the reactivity of thiol groups, the biocompatibility of PEG segments, and the fluorescent labeling properties of dansyl chloride. Its core value lies in serving as an efficient catalyst or linking arm, being widely used in bioconjugation, surface modification of materials, and construction of functionalized molecules, especially suitable for the preparation of pharmaceutical intermediates requiring precise control of molecular weight.
