This chemical is widely used in the field of bioconjugation and surface modification. It serves as a linker molecule, enabling the attachment of biomolecules like proteins, peptides, or antibodies to various surfaces or other molecules. Its triethylene glycol (TEG) spacer provides flexibility and reduces steric hindrance, enhancing the efficiency of binding interactions. The carboxyl group (-COOH) allows for easy functionalization, making it suitable for applications in drug delivery systems, biosensors, and diagnostic assays. Additionally, it is utilized in the development of hydrogels and nanomaterials, where its properties improve biocompatibility and stability.
