Used as a crosslinking agent in polymer chemistry, particularly in the development of hydrogels and biocompatible materials for drug delivery systems. Its multi-ether and amide-rich structure enables solubility in aqueous and polar organic media, making it suitable for conjugation with biomolecules and functionalization of surfaces in biomedical applications. Frequently employed in the synthesis of smart materials due to its flexibility, hydrophilicity, and ability to form stable networks. Also utilized in coatings and adhesives where enhanced flexibility and moisture resistance are required.
