I. [Product Description]
FA-PEG-serine is an organic intermediate of polyethylene glycol-serine based on folic acid targeting modification. It has excellent biocompatibility and amphiphilic structure, and is widely used in the synthesis of pharmaceutical intermediates and the catalytic coupling of polymer materials. Its molecular design combines the steric hindrance effect of the PEG segment and the active functional groups of serine, which can significantly improve the stability of the complex and the efficiency of functional modification.
