I. [Product Description]
FA-PEG-Biotin is a multifunctional organic intermediate prepared by the efficient coupling technology of folic acid (FA), polyethylene glycol (PEG), and biotin. It has excellent water solubility and biocompatibility. This compound can be used as a pharmaceutical intermediate for the construction of targeted molecular carriers. The PEG segment provides a steric hindrance effect, and the biotin module enables efficient binding to the avidin system. It is widely used in bioconjugation and nanocatalysis systems.
