Used in peptide synthesis and bioconjugation processes, this compound acts as a protecting group reagent, particularly for amines. Its disulfide bond allows for reversible linkage under mild reducing conditions, making it valuable in the development of pharmaceuticals and biotechnological applications where controlled release or reversible modification is needed. It is also employed in the preparation of functionalized surfaces for biosensors and in the stabilization of intermediate compounds during multistep organic syntheses.
