Used extensively in bioconjugation and click chemistry applications, it serves as a linker to connect biomolecules with high specificity and efficiency. Its PEG spacer enhances solubility and reduces steric hindrance, making it ideal for labeling proteins, peptides, and antibodies in research and diagnostics. It is also employed in drug delivery systems to create targeted therapies by attaching payloads to targeting ligands. Additionally, it plays a role in material science for surface modifications and functionalization of nanoparticles or polymers. Its dual DBCO groups enable simultaneous conjugation, facilitating the creation of complex molecular architectures.
