I. [Product Description] 
SAS-PEG-NTA Alkyl Sulfonate-Polyethylene Glycol-Nitrilotriacetic Acid is a multifunctional organic intermediate that combines the interfacial activity of alkyl sulfonates with the metal-chelating ability of NTA groups. Excellent water solubility and biocompatibility adjustment are achieved through the PEG segment. This compound can be used as a pharmaceutical intermediate for the modification of functional materials or as a catalyst carrier, playing an important role in the field of coordination chemistry.
