Used in biochemical research as a linker or functionalized building block for protein conjugation and bioconjugation techniques. Its disulfide bond allows reversible attachment to thiol groups, making it useful in the design of cleavable drug delivery systems and targeted therapeutics. The pyridine and carbamoyl functionalities enhance solubility and enable coordination with metals or participation in catalytic systems. It is also employed in the synthesis of peptide mimetics and enzyme inhibitors where controlled release or redox sensitivity is required.
