I. [Product Description]
SAS-PEG-COOH (Alkyl Sulfonate-Polyethylene Glycol-Carboxyl) is a multifunctional amphiphilic organic intermediate with dual reactive sites of sulfonic acid groups and carboxyl groups. It can be used as a pharmaceutical intermediate to construct functional molecular carriers. Its PEG segment provides excellent water solubility and biocompatibility, and its adjustable molecular weight characteristic makes it show significant application value in catalytic system design and nanomaterial preparation.
