This chemical is widely used as a linker in bioconjugation processes, particularly in the development of antibody-drug conjugates (ADCs). It facilitates the formation of disulfide bonds between drug molecules and antibodies, enabling targeted drug delivery to specific cells, such as cancer cells. Additionally, it is employed in protein modification studies to introduce thiol-reactive groups, aiding in the study of protein interactions and functions. Its applications also extend to the preparation of functionalized surfaces for biosensors, where it helps immobilize biomolecules for detection purposes.
