I. [Product Description]
    BSA-PEG-Tosyl (Tosylate) is a multifunctional organic intermediate. Through the precise coupling of bovine serum albumin (BSA) and polyethylene glycol (PEG), the terminal is modified with a tosylate group, combining biocompatibility and chemical activity. This compound can serve as an efficient pharmaceutical intermediate and act as a catalyst carrier in coupling reactions, significantly enhancing the stability and functional modification efficiency of biological macromolecules.
