This compound is widely used in bioconjugation and chemical biology for attaching molecules to proteins, peptides, or other biomolecules. Its PEG (polyethylene glycol) spacer enhances solubility and reduces steric hindrance, making it useful in drug delivery systems to improve the pharmacokinetics of therapeutic agents. It is also employed in the development of antibody-drug conjugates (ADCs), where it serves as a linker to connect cytotoxic drugs to antibodies, enabling targeted cancer therapy. Additionally, it is utilized in the modification of surfaces for biosensors, facilitating the immobilization of biomolecules for diagnostic applications. Its reactive bromoacetamide group allows for specific and stable conjugation with thiol-containing molecules, making it valuable in research and industrial applications.
