Used as a key intermediate in the synthesis of pharmaceuticals and functional materials, this compound is particularly valuable in modifying biomolecules and drug delivery systems due to its flexible polyether chain and terminal amine group. The amine allows for easy conjugation with carboxylic acids or activated esters, making it useful in bioconjugation chemistry, such as in the development of PEG-like linkers for antibody-drug conjugates (ADCs) or targeted therapies. Its hydrophilic polyether backbone enhances solubility and biocompatibility, which is beneficial in improving the pharmacokinetic properties of drug molecules. It is also employed in surface modification of nanoparticles and polymers, where controlled hydrophilicity and reactive anchoring points are required.
