I. [Product Description]
Tosylate-PEG-CHEMS is a multifunctional organic intermediate composed of a tosylate active group, a polyethylene glycol (PEG) chain, and cholesteryl hemisuccinate (CHEMS). It combines high coupling ability with biocompatibility. Its molecular design allows for the adjustment of the hydrophilic-lipophilic balance through the PEG chain. It is suitable for the preparation of nanocarriers, the modification of polymer materials, and the construction of catalyst systems in bioconjugation reactions, and has significant application value in the field of pharmaceutical intermediate development.
