I. [Product Description]
Tosyl-PEG-Dansyl is a multifunctional triblock compound that combines the high reactivity of the tosyl group, the biocompatibility of the PEG chain, and the fluorescence properties of dansyl chloride. It can be used as an organic intermediate for bioconjugation reactions and material surface modification. Its unique bifunctional group design gives it significant advantages in the construction of drug carriers and the synthesis of functional polymers.

III. [Application Areas]
1. Synthesis of fluorescent labeling probes (based on the fluorescence properties of dansyl chloride)
2. Hydrophilic-hydrophobic modification of polymer materials (regulation of surface properties by the PEG segment)
3. Biomolecular cross-linking agent (reaction of the tosyl group with amino/thiol groups)
4. Functional modification of nanocarrier drug delivery systems (enhancement of biocompatibility by PEG)
5. Bifunctional linking arm in organic synthesis (simultaneous introduction of reactive groups)
