I. [Product Description]
Tosyl-PEG-PAE is an amphiphilic block copolymer composed of a tosyl (Tosyl) reactive group, a polyethylene glycol (PEG) segment, and a poly(β-amino ester) (PAE). It combines the high reactivity of organic intermediates with the structural designability of pharmaceutical intermediates. Its Tosyl group can serve as an efficient catalyst carrier or a site for functional modification, suitable for the precise construction of complex molecular systems.
