SPDH is a heterobifunctional crosslinking reagent featuring an N-hydroxysuccinimide (NHS) ester and a pyridyldisulfide group, connected by a hexanoate spacer. It is primarily used as a pharmaceutical intermediate for bioconjugation, enabling the formation of cleavable disulfide bonds between biomolecules.
