I. [Product Description]
C18-PEG-COOH is an organic intermediate with an amphiphilic structure. Its octadecyl chain segment provides hydrophobic anchoring, and the carboxyl group endows the molecule with modifiable active sites. Coupled with the PEG chain segment with adjustable molecular weight, it shows excellent performance in the self-assembly of nanomaterials, interface modification, and the construction of catalytic carriers. This compound combines biocompatibility with molecular structure designability and is a key pharmaceutical intermediate for the development of functional materials.
