Used as a specialized intermediate in organic synthesis, particularly in the preparation of functionalized polymers and dendrimers. Its tosylate group acts as a good leaving group, enabling efficient coupling reactions with nucleophiles such as amines or thiols. The triphenyl and polyether segments provide steric bulk and solubility in polar organic solvents, making it useful in phase-transfer catalysis and as a building block for supramolecular structures. Also employed in the development of surface modifiers for nanoparticles, where controlled grafting density is required.
