I. [Product Description]
Tosyl-PEG-PASP is a triblock copolymer with tosyl as the activated end group. It combines the biocompatibility of polyethylene glycol and the structural modifiability of polyaspartic acid, making it an excellent organic intermediate for constructing targeted carriers. Through precise molecular weight control and functional group design, this compound demonstrates unique application value in the fields of pharmaceutical intermediate synthesis, surface modification of nanomaterials, and catalyst immobilization.
