Boc-Cystamine Hydrochloride is a key reagent in peptide and protein synthesis, featuring a central disulfide bond and a Boc-protected amine group. It serves as a bifunctional linker, enabling the formation of disulfide cross-links that can be selectively cleaved under reducing conditions. This property makes it valuable for constructing complex peptides and proteins with controlled disulfide bonding. It is widely used in drug delivery systems to create cleavable linkages for targeted therapeutic release. Additionally, Boc-Cystamine Hydrochloride facilitates bioconjugation by allowing the attachment of biomolecules to surfaces, nanoparticles, or other molecules for research, diagnostics, and material science applications. Its role in cross-linking further supports studies of protein structures, folding, and interactions.
