Used extensively in bioconjugation and chemical synthesis, it serves as a linker to attach molecules or modify surfaces. In drug delivery, it facilitates the creation of PEGylated compounds, enhancing solubility and stability of therapeutic agents. It’s also employed in material science for surface functionalization, improving biocompatibility of polymers and nanoparticles. Additionally, it plays a role in cross-linking reactions for hydrogel formation, useful in tissue engineering and controlled-release systems. Its dual bromide groups make it a versatile reagent for introducing polyethylene glycol (PEG) chains into various molecular structures.
