I. [Product Description]
Casein-PEG-Tosyl (Tosylate) is a multifunctional organic intermediate. Through the covalent coupling of casein with polyethylene glycol (PEG) and the functional modification of tosylate, it combines biocompatibility and reactivity. Its core value lies in serving as an efficient catalyst carrier or pharmaceutical intermediate, suitable for fields such as bioconjugation reactions, polymer material synthesis, and surface functional modification.
