I. [Product Description]
HSA-PEG-Acetylthio is a functionalized biopolymer prepared by precise coupling technology. It is widely used as an organic intermediate in the bio-coupling reaction system. Its core value lies in the excellent water solubility and steric hindrance effect conferred by the PEG segment, combined with the high reactivity of the acetylthio group. It is particularly suitable for the synthesis of pharmaceutical intermediates and the construction of catalyst carriers, enabling precise thiol-directed coupling reactions.
