I. [Product Description]
Tosylate-PEG-Niacin is a multifunctional organic intermediate that combines the high reactivity of tosylate, the excellent water solubility and biocompatibility of polyethylene glycol (PEG), and the functional group characteristics of niacin. It is widely used in polymer modification, drug delivery system development, and catalytic reaction systems. This product can be used as a pharmaceutical intermediate or a catalyst carrier, significantly improving the efficiency of coupling reactions and the stability of target products.
