This chemical is primarily used as a linker or cross-linking agent in bioconjugation and chemical synthesis. It is particularly valuable in attaching functional groups or biomolecules, such as proteins or peptides, to surfaces or other molecules. Its reactive groups, including the NHS ester and carboxylic acid, enable efficient coupling reactions under mild conditions. This makes it suitable for applications in drug delivery systems, where it can help create stable conjugates for targeted therapies. Additionally, it is utilized in the development of biosensors and diagnostic tools, where precise molecular attachment is critical for accurate detection and analysis. Its versatility also extends to material science, where it aids in modifying surfaces for enhanced biocompatibility or specific interactions.
