Application

m-PEG2-Br, 98% (stabilized with Na₂CO₃) serves as a versatile bifunctional linker for conjugation and polymer functionalization. Its terminal bromide enables efficient coupling with nucleophilic groups such as amines and thiols under mild conditions. The methoxy-terminated PEG spacer provides excellent solubility and stability in aqueous and organic media, facilitating purification and minimizing non-specific interactions. Ideal for synthesizing bioconjugates, drug delivery systems, and surface-modified materials.
