I. [Product Introduction]
Mal-PEG-Biotin is a multifunctional organic intermediate composed of a maleimide group, a polyethylene glycol (PEG) chain, and a biotin group. It is suitable for bioconjugation and molecular probe construction. Its unique bifunctional structure can serve as an efficient coupling catalyst, demonstrating excellent reactivity and stability in biolabeling and nanomaterial synthesis. It is a key material for the development of pharmaceutical intermediates.
