Used as a bifunctional crosslinking agent in polymer chemistry, particularly in the development of hydrogels and bioconjugates. Its terminal NHS ester groups react efficiently with primary amines on proteins, peptides, or amine-functionalized polymers, enabling the formation of stable amide bonds. This compound is especially valuable in drug delivery systems and tissue engineering, where controlled network formation and biocompatibility are essential. The long aliphatic chain spacer provides flexibility and enhances accessibility between reactive sites, improving conjugation efficiency. It is also employed in surface modification of biomaterials to immobilize bioactive molecules.
