I. [Product Introduction]
FA-PEG-threonine is a functionalized organic intermediate formed by the covalent bonding of folic acid (FA), polyethylene glycol (PEG), and threonine. It combines targeting, water solubility, and biocompatibility, and can be used as a pharmaceutical intermediate or catalyst carrier in high-precision bioconjugation systems. The PEG segment in its molecular structure effectively enhances the dissolution stability, and the threonine residue provides active sites for directional modification.
