Azido-PEG-Bromide
Azido-PEG-Bromide is a heterobifunctional PEG reagent, also known as Azide-functional PEG-bromide, featuring an azide group for copper-catalyzed click chemistry and a bromide terminus for nucleophilic substitution reactions. The bromide group enables efficient alkylation of thiols or amines, while the azide allows subsequent cycloaddition with alkynes. Azido-PEG-Bromide reagents are ideal for synthesizing functionalized polymers, surface-modified nanoparticles, and complex biomolecular conjugates.
