Used in organic synthesis to introduce sulfhydryl groups into molecules, enabling the creation of thiol-containing compounds. Applied in the development of pharmaceuticals, where it serves as a building block for drugs targeting various diseases. Utilized in peptide chemistry for modifying amino acids or peptides to enhance their biological activity or stability. Also employed in material science for surface functionalization, improving adhesion or compatibility of materials in coatings and polymers. Plays a role in biochemical research as a reagent for studying enzyme mechanisms or protein interactions involving thiol groups.
