Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of compounds targeting cardiovascular and neurological disorders. It serves as a precursor in the preparation of homocysteine-related metabolites for research on oxidative stress and metabolic pathways. Also utilized in studies investigating protein modification and enzyme inhibition due to its reactive thiol group. Its thiolactone structure makes it valuable in organic synthesis for ring-opening reactions and the formation of thioether bonds.
