This chemical is primarily used in organic synthesis as a versatile building block for the preparation of complex molecules. It is particularly valuable in the development of polyethylene glycol (PEG) derivatives, which are widely employed in pharmaceuticals, biotechnology, and material science. The bromo group facilitates further functionalization through nucleophilic substitution reactions, enabling the attachment of various moieties. Its application extends to the creation of drug delivery systems, where PEGylation enhances the solubility, stability, and bioavailability of therapeutic agents. Additionally, it serves as a precursor in the synthesis of surfactants and polymers with tailored properties for industrial and research purposes.
