I. [Product Description]
FA-PEG-VS (Folic acid-polyethylene glycol-vinyl sulfone) is a high-purity organic intermediate with both targeted molecular modification and efficient coupling functions. Its core value lies in the specific binding through the folic acid group. Combining the excellent water solubility and biocompatibility of the PEG chain, it can be used as a catalyst or a linking arm in the construction of complex molecules and is a key pharmaceutical intermediate for bioconjugation and nanomaterial synthesis.
