Description

m-PEG5-Br features a five-ethylene glycol unit spacer flanked by a reactive bromide at one end and a methoxy group at the other. This bifunctional architecture enables site-specific conjugation in bioconjugation workflows while maintaining solubility and stability under standard conditions.

Application

m-PEG5-Br serves as a versatile bifunctional linker for conjugation and polymer functionalization, enabling efficient coupling of biomolecules, drugs, and surface-bound reagents. Its terminal bromide group undergoes reliable nucleophilic substitution with amines, thiols, and other nucleophiles under mild conditions, while the central PEG5 chain provides excellent solubility and reduced non-specific binding. The compound exhibits robust bench stability, facilitates straightforward purification, and supports scalable synthesis in drug delivery and materials science applications.
