Used as a linker molecule in organic synthesis, particularly in the preparation of functionalized polymers and dendrimers. Its bromine end groups readily undergo nucleophilic substitution, allowing attachment to other molecules or surfaces. Commonly employed in pharmaceutical research and material science to bridge hydrophilic segments due to the presence of ether linkages, enhancing solubility in polar media. Also utilized in the synthesis of crown ether analogs and as a spacer in supramolecular chemistry.
