Description

Br-PEG4-OH is a bifunctional PEG linker featuring a bromo group at one terminus and a hydroxyl function at the other. This combination enables selective conjugation reactions while maintaining solubility in aqueous and organic media. The molecule integrates readily into bioconjugation workflows, offering a robust handle for site-specific modifications in peptide and protein engineering.

Application

Br-PEG4-OH serves as a versatile bifunctional building block for conjugation and polymer synthesis, enabling efficient coupling of biomolecules, drug candidates, or surface-functionalized materials. The terminal bromide reacts selectively with nucleophiles under mild conditions, while the hydroxyl group offers additional handle for derivatization. Its PEG4 spacer provides enhanced solubility and reduced non-specific binding in biological systems, making it ideal for applications in medicinal chemistry, bioconjugation, and material science.
