I. [Product Description]
SAS-PEG-NBD (Alkyl Sulfonate-Polyethylene Glycol-Nitrobenzoxadiazole) is a multifunctional organic intermediate that combines the ionic properties of alkyl sulfonates with the fluorescent labeling function of nitrobenzoxadiazole (NBD). It is widely used in the synthesis of pharmaceutical intermediates and catalytic reaction systems. Its polyethylene glycol (PEG) segment endows the molecule with excellent water solubility and biocompatibility, making it suitable for functional modification in complex chemical environments.

III. [Application Fields]
1. Fluorescent probe labeling: The NBD group is suitable for the fluorescent tracing research of biomolecules or nanomaterials.
2. Polymer material modification: The PEG segment can adjust the hydrophilic-hydrophobic balance and interfacial properties of materials.
3. Surfactant development: The alkyl sulfonate structure facilitates the design of amphiphilic molecules.
4. Nanocarrier construction: Targeted functional modification can be achieved through the sulfonic acid group.
5. Organic synthesis catalyst: Combine the phase-transfer catalytic properties of PEG with the electronic effect of NBD.
