I. [Product Introduction]
Br-PEG-MAL (Bromide-Polyethylene Glycol-Maleimide) is a multifunctional organic intermediate that combines the high reactivity of bromide and the biocompatibility of the PEG chain. The maleimide group can specifically conjugate with thiol compounds. This compound serves as an efficient catalyst and cross-linking agent, and is widely used in the fields of biomaterial modification, polymer synthesis, and nanoparticle functionalization.
