I. [Product Description]
FA-PEG-COOH (Folic acid-Polyethylene glycol-Carboxyl) is a multifunctional organic intermediate. Through the synergistic action of the folic acid targeting group and the carboxyl active group, it has important value in biological coupling, nanomaterial modification, and catalyst support construction. Its PEG segment provides excellent water solubility and biocompatibility, and can be used as a pharmaceutical intermediate for functional molecule design.
