I. [Product Description]
Tosylate-PEG-PBA is a multifunctional organic intermediate with both the development potential of pharmaceutical intermediates and the functional characteristics of catalytic carriers. The tosylate group in its molecular structure provides high-efficiency coupling activity, the phenylboronic acid (PBA) group imparts specific recognition ability, and the PEG chain significantly improves water solubility and biocompatibility. It is suitable for the directional modification and functional construction of complex synthetic systems.
