I. [Product Description]
SS-PEG-Mal (Disulfide-Polyethylene Glycol-Maleimide) is a multifunctional organic intermediate that combines a cleavable disulfide bond structure, a highly biocompatible PEG chain, and the efficient coupling characteristics of maleimide. It is widely used in the fields of bioconjugation, nanomaterial synthesis, and polymer functionalization. Its modular design can be used as a catalyst or cross-linking agent, significantly enhancing the controllability of the reaction and the stability of the product. It is an ideal choice for the development of pharmaceutical intermediates and the research of functional materials.
