Used primarily in biochemical research and pharmaceutical development as a protective agent for thiol groups in peptides and proteins. It helps in preventing unwanted reactions during synthesis, ensuring the integrity and functionality of the final product. Additionally, it serves as a precursor in the production of specific cysteine derivatives, which are valuable in studying enzyme mechanisms and protein interactions. Its application is also seen in the development of drugs targeting oxidative stress and inflammation, due to its ability to modulate cellular redox states.
