Bis-Bromo PEG

Br-PEGn-Br is a homobifunctional alkylating agent widely used for crosslinking nucleophilic groups (e.g., thiols or amines) in polymers, hydrogels, and biomolecular conjugates. Its key advantages include symmetric reactivity for efficient networking, tunable spacer length (n), and cost-effective synthesis, though the bromide groups are highly moisture-sensitive and require strict anhydrous handling to prevent hydrolysis.
