I. [Product Description]
Tosyl-PEG-PBA is a functionalized polyethylene glycol derivative with a tosyl group as the active end group and a phenylboronic acid as the functional group. As a high-performance organic intermediate and pharmaceutical intermediate, it has both excellent water solubility and precise coupling ability. The tunability of the PEG chain in its molecular structure and the specific binding characteristics of the boronic acid group make it of great application value in the fields of bioconjugation, targeted modification, and catalytic carrier construction.
