I. [Product Description]
SA-PEG-FA (Stearic Acid-Polyethylene Glycol-Folic Acid) is a functionalized polymer compound with an amphiphilic structure. As a high-performance organic intermediate and pharmaceutical intermediate, it is widely used in the construction of targeted delivery systems. Its unique molecular design combines a hydrophobic stearic acid segment, a flexible PEG segment, and a targeted folic acid group. It exhibits excellent stability and controllability in nanomaterial preparation and bioconjugation reactions, and can be used as a catalyst carrier or a key component for functional modification.
