I. [Product Description]
Tosyl-PEG-PAA is a multifunctional block copolymer that combines the high reactivity of the tosyl group, the biocompatibility of the PEG chain, and the pH-responsive property of PAA. It can be used as an organic intermediate or a catalyst carrier and is widely applied in the synthesis and functional modification of polymer materials. Its unique amphiphilic structure and adjustable molecular weight parameters provide core material support for the precise construction of functional nanosystems.

II. [Product Details]
