I. [Product Description]
VA-PEG-PFP is a valeric acid-modified polyethylene glycol pentafluorophenol active ester, widely used as a high-performance organic intermediate in the fields of bioconjugation and polymer modification. Its core value lies in the precise regulation of hydrophilicity and hydrophobicity through the adjustable molecular weight of the PEG chain. Meanwhile, the pentafluorophenol active group endows it with excellent catalytic coupling efficiency, making it particularly suitable for the preparation of pharmaceutical intermediates and the synthesis of polymer materials that require mild reaction conditions.
