This compound is widely used in bioconjugation and chemical biology research. It serves as a linker molecule, enabling the attachment of various biomolecules, such as peptides, proteins, or antibodies, to other functional groups or surfaces. Its PEG (polyethylene glycol) spacer provides flexibility and solubility, which is crucial for maintaining the stability and functionality of the conjugated molecules. It is particularly valuable in drug delivery systems, where it helps create targeted therapies by linking drugs to specific carriers or antibodies. Additionally, it is employed in the development of diagnostic tools, such as fluorescent probes or imaging agents, to enhance detection and visualization in biomedical studies.
