Used as a key building block in the synthesis of advanced polymers and dendrimers due to its long, flexible chain with multiple ether linkages and terminal amine groups. The compound enables the creation of highly branched macromolecules with precise architectures, useful in drug delivery systems and nanotechnology. Its hydrophilic nature and ability to form complexes with metal ions make it suitable for applications in molecular recognition and catalysis. Also employed in surface modification of nanoparticles and in the development of specialty coatings where controlled spacing of functional groups is required.
