I. [Product Description]
FA-PEG-SG (Succinimidyl Glutarate-Polyethylene Glycol-Folic Acid) is a multifunctional organic intermediate. It achieves targeted functional modification of folic acid through precise PEG coupling technology. Its core value lies in excellent biocompatibility and controllable molecular weight distribution. It can be used as a pharmaceutical intermediate to construct high-stability composite systems, or as an amphiphilic carrier in catalytic reactions to improve reaction efficiency.
