Used as a ligand in coordination chemistry, particularly in the formation of metal complexes with transition metals. Its structure allows for strong chelating interactions due to the presence of multiple nitrogen donors and a thiol group, making it effective in catalysis and metal ion sensing applications. Commonly employed in the development of homogeneous catalysts for organic transformations such as oxidation and coupling reactions. Also investigated for use in biochemical research as a metal sequestering agent or in the design of enzyme inhibitors. The thiol functionality enables surface binding on gold nanoparticles, useful in nanomaterials and sensor design.
