This chemical is widely used in the field of bioconjugation and drug delivery due to its polyethylene glycol (PEG) spacer. The PEG chain enhances solubility and reduces immunogenicity, making it ideal for modifying proteins, peptides, and other biomolecules. It is often employed in the development of therapeutic agents, where it helps improve stability and prolong circulation time in the body. Additionally, its amine groups allow for easy conjugation with various functional groups, facilitating the creation of targeted drug delivery systems. It is also utilized in the synthesis of hydrogels and other biocompatible materials for medical and research applications.
