Used as a crosslinking agent in bioconjugation processes, it facilitates the attachment of biomolecules such as proteins, peptides, or antibodies to other molecules or surfaces. The azide group enables click chemistry reactions, particularly with alkynes, to form stable triazole linkages. The NHS ester group reacts with primary amines, allowing covalent bonding to amino groups in target molecules. This compound is particularly useful in drug delivery systems, where it helps in creating targeted therapeutic agents by linking drugs to carriers like nanoparticles or antibodies. It also plays a role in surface modification, enabling the functionalization of materials for biosensors or diagnostic assays. Additionally, it is employed in the development of bioconjugated probes for imaging and detection in biological research.
