Used as a crosslinking agent in biomaterials and hydrogels, particularly in tissue engineering and drug delivery systems. Its primary application lies in modifying polymers to enhance biocompatibility and mechanical strength. The amine and amide functional groups allow conjugation with biomolecules such as peptides or enzymes, making it valuable in biosensor development and bioconjugation chemistry. Also employed in the synthesis of functionalized surfaces for diagnostic devices and medical coatings due to its spacer-like properties that improve molecular accessibility.
