I. [Product Description]
Tosyl-PEG-Poly-Sarcosines is a multifunctional organic intermediate composed of a tosyl-activated end group, a polyethylene glycol (PEG) chain segment with adjustable molecular weight, and poly-sarcosine with excellent biocompatibility. It is widely used in the field of polymer material modification and functionalization. Its unique structural design allows it to serve as an efficient catalyst carrier or pharmaceutical intermediate and performs outstandingly in the construction of nanodelivery systems and surface functionalization modification.
