Used primarily as a reagent in organic synthesis, particularly in the development of disulfide-containing compounds. It serves as a key intermediate in the preparation of biologically active molecules, including pharmaceuticals and agrochemicals, where disulfide bridges are essential for structural stability or function. Its bromo and acetate functional groups allow for selective reactions, enabling stepwise construction of complex molecules. Commonly applied in the synthesis of peptides, enzyme inhibitors, and functionalized polymers. Also utilized in biochemical research for modifying thiol groups in proteins and nucleic acids due to its ability to form reversible disulfide bonds.
